Started seeing this last Friday, Jun 26, 2019,
in a clients PowerApps Environment.
This behavior is present in both
Microsoft Edge and Chrome Browsers
While in the Web Editor:
The Screen shrinks to Editor size but the side panels,
the Screens Tree view and the Properties panels are both missing and main menus do nothing.
Close button is also disabled.
Only recourse is to close the app and launch once more.
Clearing all cache in either browers has no affect.
Fortunatley Production app is not affected.
Chrome: Version 75.0.3770.100
Microsoft Edge: 42.17134.1.0
PowerApps Version: 3.19062.18
I don't know if this may be related or not but a couple hours ago I had the last 3 screens disappear off my tree. They simply weren't there. I knew I had not deleted them. I closed the app and restarted and they were where they were supposed to be again.
I'm also seeing this issue.
The navigation and property panes become unresponsive or disappear altogether and the activiy indicator runs constantly. Only option is to close and reopen Studio in the browser.
App runs fine in Web and Android players.
First noticed it sometime last week.
Update: Deleted all the data tables in my App (was only using them to view the state of variables during testing) and so far the problem appears to be resolved for me.
