web powerapps stopped working

I have been working on apps this morning and testing using web 'Play' - suddenly it has stopped working - this list of apps is vsible, but if I right click on any of the apps (including ones I haven't changed today ) a blank screen opens up (with the background colour of the app, but no content).

 

I have rebooted the machine (Windows 10) and tried on a different machine but no luck.

 

Is web play working for others, or has anyone got any ideas as to what has gone wrong?

My team are seeing the same behaviour - we also had this intermittently last week but it resolved itself. Today its been unavialble all day in web player with the Demo Apps showing the same blank screen.

 

If I try and run them in the Win 10 native player then it works as expected.

Hi all, I also have the same behaviour.

I suspect that there is an upgrade in progress...

We are aware of this issue and it is actively being worked on.

 

The related issue can be found at https://powerusers.microsoft.com/t5/PowerApps-Forum/PowerApps-web-player-not-loading-apps/m-p/17501#....

 

Please try again and let us know if you are still experiencing the issue.

 

Sorry for the inconvenience.

 

Ryan McHenry [MSFT - PowerApps]

Sorry everyone for the inconvenience!

 

We were able to identify the problem and just pushed a fix out. This should now be fully resolved, and apps should launch successfully again.

 

If anyone is still seeing this issue, please let us know.

Thanks Ryan,

 

Now this is out of Beta and a production system shouldn't there be monitoring on the system to identify and alert you to an issue rather rely on users to report the problem?

 

We lost pretty much a full day yesterday and had similar problems intermittently last week?

 

I'm not sure if the comments on here propmted someone to look at this, I'm fortunate to have a route through or development partner into the product team so could escalate this.

 

What can you reassure about future stability?

Hi JonT,


Your concerns are valid, and you are absolutely correct that we should have caught this with automatic monitoring. Additionally, we should have been able to resolve this sooner once it started happening.

 

To provide some background, we do have automatic monitoring in place to catch issues like these, but it unfortunately didn’t catch this issue in a timely fashion.

 

Since this was resolved yesterday, we’ve been investigating exactly why our monitoring missed this, and we have shifted gears to prioritize putting additional safeguards and a more robust alerting/mitigating story in place.

 

Specifically, we are now working on three main fixes that we plan to roll out over the next few weeks:

 

  1. Alerting on this type of outage – we are fixing up our automatic alerts to detect this issue immediately in the future, so that if it ever crops up again, it will engage our on-call/support staff before it starts affecting users.

     

  2. Faster mitigation – in the short term, we are adding guidelines for our support staff to manually fix issues like this more quickly, so that the fix will (ideally) take minutes instead of hours. Longer term, we are going to work on trying to have are monitoring system automatically mitigate the issue when it’s detected.

     

  3. A more preventative fix for the root problem – this core issue was caused by some larger problems with our CDN configuration. We are making some changes to our CDN setup to hopefully guard against this in the future.

     

Between all three of these, we are hoping to prevent outages like this entirely.

 

Generally speaking, I can assure you that we take reliability very seriously, and we understand that outages like we saw yesterday are unacceptable. We are constantly working to improve in this area, and we will do everything we can to prevent downtime going forward.

 

Sorry again for the inconvenience.

 

Ryan Jansen [MSFT]

Tuesday Tip: Subscriptions & Notifications

TUESDAY TIPS are our way of communicating helpful things we've learned or shared that have helped members of the Community. Whether you're just getting started or you're a seasoned pro, Tuesday Tips will help you know where to go, what to look for, and navigate your way through the ever-growing--and ever-changing--world of the Power Platform Community! We cover basics about the Community, provide a few "insider tips" to make your experience even better, and share best practices gleaned from our most active community members and Super Users.   With so many new Community members joining us each week, we'll also review a few of our "best practices" so you know just "how" the Community works, so make sure to watch the News & Announcements each week for the latest and greatest Tuesday Tips!   This Week: All About Subscriptions & Notifications We don't want you to a miss a thing in the Community! The best way to make sure you know what's going on in the News & Announcements, to blogs you follow, or forums and galleries you're interested in is to subscribe! These subscriptions ensure you receive automated messages about the most recent posts and replies. Even better, there are multiple ways you can subscribe to content and boards in the community! (Please note: if you have created an AAD (Azure Active Directory) account you won't be able to receive e-mail notifications.)   Subscribing to a Category  When you're looking at the entire category, select from the Options drop down and choose Subscribe.     You can then choose to Subscribe to all of the boards or select only the boards you want to receive notifications. When you're satisfied with your choices, click Save.   Subscribing to a Topic You can also subscribe to a single topic by clicking Subscribe from the Options drop down menu, while you are viewing the topic or in the General board overview, respectively.     Subscribing to a Label Find the labels at the bottom left of a post.From a particular post with a label, click on the label to filter by that label. This opens a window containing a list of posts with the label you have selected. Click Subscribe.           Note: You can only subscribe to a label at the board level. If you subscribe to a label named 'Copilot' at board #1, it will not automatically subscribe you to an identically named label at board #2. You will have to subscribe twice, once at each board.   Bookmarks Just like you can subscribe to topics and categories, you can also bookmark topics and boards from the same menus! Simply go to the Topic Options drop down menu to bookmark a topic or the Options drop down to bookmark a board. The difference between subscribing and bookmarking is that subscriptions provide you with notifications, whereas bookmarks provide you a static way of easily accessing your favorite boards from the My subscriptions area.   Managing & Viewing Your Subscriptions & Bookmarks To manage your subscriptions, click on your avatar and select My subscriptions from the drop-down menu.     From the Subscriptions & Notifications tab, you can manage your subscriptions, including your e-mail subscription options, your bookmarks, your notification settings, and your email notification format.     You can see a list of all your subscriptions and bookmarks and choose which ones to delete, either individually or in bulk, by checking multiple boxes.     A Note on Following Friends on Mobile Adding someone as a friend or selecting Follow in the mobile view does not allow you to subscribe to their activity feed. You will merely be able to see your friends’ biography, other personal information, or online status, and send messages more quickly by choosing who to send the message to from a list, as opposed to having to search by username.
