App sometimes won't load

I've seen sometimes users have problem to open an app, when they use directly app link from bookmarks (not from a portal).
They don't get further than initial loading screen (the one with spinner).
Users can be waiting for few minutes, but nothing is being loaded. They try to open it again after a while, but still same problem. Usually it starts to work after 5th-6th attempt.


I've made pretty simple app for submitting requests having only 4 screens, 3 different forms, 1 connection (to SharePoint Online). Application is loading no data, this app is purely only for submitting, so there should be nothing that can cause a problem.
The only 2 commands I used in App "OnStart" are settings variables like:


Set(var_maincolor,RGBA(102, 0, 102, 1)); 


but even with simple app like that users have same problem.

I was not able to replicate the problem with my account on any of our apps.

Any idea what can be wrong or how to investigate the problem? Sometimes it works just fine, but sometimes it just get stuck and it's not isolated only to one app, but more  generic problem.

Re: App sometimes won't load

Hi @marekbuban,

Have you considered comparing the parameters of the working apps with the ones from the not working apps? Maybe one experimental feature is causing the problem.

Also, try commenting the User() function in your application just to make sure that it's not the access to the AD that is causing the problem...

Tell us how this goes...

Thanks @R3dKap  for your answer.

I use no experimental feature in these apps.

I've tried to comment the User() function and will wait for it to be tested by users, but I doubt it will help, as other apps with same problem doesn't use that function.


Re: App sometimes won't load

Can you please provide the session ID next time this happens?  Please obtain the session ID, please follow the instruction below.


If you are not able to see the setting icon because you are stuck on the splash screen, please hit F12 key to open the developer tool of the browser.  Go to the Console window and type Core.Telemetry.Log.sessionId; and hit enter.  You should see the session ID displayed.  Thanks.
