Scroll Issues When Upgraded to 3.18062.26

Hi, I have a PowerApp that is behaving undesirably after the recent update.  Some notes about this app:

 

Prior to Update

  1. App was on version 3.18061.15
  2. App uses Sharepoint lists for data (including some that are used to drive cascaded dropdown fields)
  3. Edit form screen scrolling is smooth and very fluid
  4. Several Yes/No toggle switches drive the visibility of other text fields (if yes, no comment is necessary type of behavior).  This is done by setting the textbox's datacard's visibility formula to the .Value of the toggle switch.
  5. When toggle switches are changed, the screen does not scroll, even though new fields are added / removed.

If I open the application in the designer and save it (making no change other than the text of a label, so that I have the save and publish option) a few things occur:

 

After Update

  1. App is updated to version 3.18062.26
  2. Edit form screen scrolling is now very choppy, sometimes it takes 2-3 swipes to get it to scroll on an iOS device
  3. Changing toggle fields that change the visibility of other fields now causes the form to scroll back to the top of the screen.
  4. These new behaviors go away if I switch the app to Classic render mode (File -> App Settings -> Advanced Settings -> Render in classic mode) or if I use version control to roll the prior version back.

My Questions

  1. Is there a way I can avoid the "Scroll to top" and choppy screen scrolling without using classic mode?  
  2. How long will classic mode be available?  Is this expected to go away in the future?
  3. Are there release notes specifically for the 3.18062.26 release?  I have only been able to find these which do not seem to include the recent changes.

Thanks in advance,

Joey

1807.3 should be deployed everywhere, can you try to disable render in classic mode and republish the app ?

 

Thanks

Hi @keathley,

 

I cannot reproduce your issue. Even when the classic mode is off, in PowerApps mobile app on iOS, the scrolling works just fine. 

 

Also, please describe in detail about what did you mean by "Changing toggle fields that change the visibility of other fields". Please share the related formulas and controls. Is this happening inside a Edit Form?

 

So far there is no such offical statement about cancelling the classic mode option.

 

Regards,

Mona

Re: Scroll Issues When Upgraded to 3.18062.26

@v-monli-msft

 

I have created everything brand new this morning (new sharepoint list, and new powerapp) to recreate the issue myself.  Below are the steps I followed.

 

  • In SharePoint O365 Online create a new list

1 Create List.png

  • Create Yes/No (toggle) columns on the list (do this x10).  Select Default value of "No"

 

2 Create YesNo Toggle Columns.png

  • Create "single line of text" comment boxes (x10 as well).  Default options ok for these.

 

3 Create Comment Columns.png

  • I turned off the "required" flag for the "title" field.  I also ordered the columns such that each toggle is next to its comment (Toggle1, Comment1, Toggle2, Comment2, etc).

4 List Columns Ordered.png

  • Use the PowerApps -> Create an app menu to create a new app.

 

5 Create PowerApp.png

 

  • Name the app

 

6 Name PowerApp.png

  • From within PowerApps select "EditForm1" from the screens list

 

7 Select EditForm1.png

 

  • Open the Data panel

 

8 Add Columns to Data.png

 

  • Turn on all of the toggles and comments, and then reorder fields such that comments follow each of their toggles (as done previously on the SharePoint side)

9 Order Columns.png

 

  • Click on each toggle switch to identify its name in the "Screen" panel.  In this example I am clicking on the toggle for "Toggle1" and see that its name is "DataCardValue10"

10 Find Name of Toggle Switch.png

 

  • Select the Comment Datacard and set its "Visible" property to the formula below (filling in the appropriate toggle name for each comment box's forumla).  Note that Comment1 will be hidden when Toggle1 is set to "Yes."  This logic follows for each comment box (Comment2 is hidden when Toggle2 is Yes, Comment3 is hidden when Toggle3 is Yes, etc.)
Not(DataCardValue10.Value)

 

11 Set Visible Property of Comment Datacard.png

 

  • Save the app

12 Save.png

 

  • Publish the app

13 Publish.png

 

  • Open the App on an iOS device (I have not tested on any other devices).  I used an iPhone 7 running 11.3, although I do not believe this matters.
  • Click the + (new record button) in the top right corner of the screen
  • Try to scroll to the bottom of the app.  You will note the choppiness of the scrolling.  
  • Change Toggle 10 from "No" to "Yes"  You will note that the form scrolls back to the top of the screen.

At this point if you:

 

  • Turn on classic Mode:

 

14 Classic Mode.png

 

  • Save & Publish again
  • Close and re-open the app on the phone at least 2 times (to ensure the latest version is downloaded)
  • Click the + (new record button) again

The issues are now gone when you use the app on your phone again.

 

Appologies to everyone for the lenght of the post, and thanks in advance for any assistance you can provide.

Thanks @AKotb was the fix included in the recent 3.18063.33 release?  If not, do you know which release it is slated for?  Thanks so much for addressing this.

if everything goes according to plan the fixes should be part of the 3.18071 release which is hopefully going to be deployed in 2 weeks.

meanwhile you can use the classic mode.

 

Thanks again for reporting this and for the detaled steps Smiley Happy

@AKotb I can confirm that the issue appears to be resoved with the 3.18073.28 release.  Thanks for the quick turn around on this issue.

Can you explain what benefits / performance enhancements the non-classic mode offers me in the Studio as well as end-users on their apps?
