I am on version 3.19054.15 and am experiencing many of the issues outlined in the above posts, namely:
Anyone else experiencing this?
@JT84 , I've looked into my own apps, in edit mode and run and they seem fine. Also created a new app with the same data source and the gallery + form were also working as intended.
This is the studio link thats provided my enviroment(tenant) https://eu.create.powerapps.com/studio/#,
Try that studio if you using another studio link. Let me know.
PS, You'll need to save your app and publish it. Close the editor then edit the app again. Thats the proccess to "upgrade" your app to new versions or the different studio links as the one provided.
I took the eu out. Orginally the above link was what we were using before the problem. I noticed after the mentioned fix by the powerapps team, the link changed to https://eu.create.powerapps.com/studio/, (I believe its a reference for europe base tenants). Give this link https://create.powerapps.com/studio/# a go. Sorry, the only other sugguestion, restore your app to the last working version.
All the best.
Thanks for your support, @Raynok1 . I am getting intermittent behaviour with my forms and variables still. I think I will start a new topic and see what happens.
@JT84 There is a bug that shipped in 3.19054 that affects a subset of apps that make use of components and/or enhanced group controls. This week's release, 3.19061, contains a fix for the bug and is currently being deployed worldwide--it will complete by end-of-day tomorrow.
For immediate mitigation, I would advise using the previous version of Studio (https://create.powerapps.com/v3.19053.21.115177711/studio/) to edit and publish the app. If the app won’t open, it will have to first be restored to a previous version that is 3.19053.x or less from the Versions tab in PowerApps portal (https://make.powerapps.com).
