First row of Gallery doesn't show after PowerApps release update to 3.19075.21

[maikeru]

Dear all,

My app was working fine until yesterday under 3.19074.24, but after I republished it today under 3.19075.21 (without any change... just added a blank space in App.OnStart), the first row of every Gallery doesn't display anymore.

After restoring the app under 3.19074.24 things are ok.

Please advise.

Best regards.
Michael

Hi v-yutliu-msft

I am on version  3.19075.20 (didnt find a version .21 on the playstore) and even I am facing the same problem here. The first item of every gallery is blank until it is loaded again or I click something.

@maikeru - How did you roll back to the previous version of powerapps app via play store? Please let me know.

Thanks,

AShep

I rolled back the application published on powerapps.com, not on the mobile client side.

Best regards.

Dear maikeru,

Sorry, I am a little confused here. Isn't the application version (which one develops on powerapps online ) different than the version of Powerapps itself?

If I understand correctly, you rolled back your app version on powerapps.com which had your development changes.

Was there an issue in the app that you have developed OR the powerapps version itself? Also, didn't rolling back undo your changes which were on the latest version?

Kindly clarify.

Thanks in advance,

AShep

To determine whether the issue was coming from PowerApps or my App, I rolled back my App to the latest point when PowerApps was still under 3.19074.24. This restored both my App former configuration and Powerapps.com former version. Once I confirmed the rollback and my app was running without issue, I republished it almost unchanged (I just entered a blank space somewhere in Apps.OnStart) under 3.19075.21. The issue appeared again.

Hope this clarifies.

Hi maikeru,

Yes, it clarifies. I checked with one of my colleagues who is running an older version of powerapps on her phone and the new app that I have published works there without any issue.

So, yes, this definitely looks to be an issue from the Powerapps side and hope it gets resolved soon.

Also, I am seeing this issue only on my mobile. The web version works fine with no issues even on the new release.

Did you see issue on both ends - mobile as well as web?

Thanks,

AShep

Thanks for the info.
Yes only mobile versions seem affected.
I have created a new (different) app from scratch today and the galleries are displaying correctly. I will try to recreate those galleries in my app to see if this helps. Will update.

@v-yutliu-msft 
After running further tests, I noticed that removing controllers referencing the Gallery in the child pages would (in some cases) help to solve the 1st row display issue. Typically my app goes from a gallery to child pages displaying further details of the selected item of the gallery using Gallery.Selected.[Name of the field].
This is in no way a solution, but perhaps it can give you some heads up to investigate the issue.

Thank you for your follow up and support!

@maikeru @AShep Can you please provide a session ID of an affected player session?  Also, what is the underlying data source that the gallery is connected to?  SQL?  SharePoint?  CDS?  etc.
