Hello!
I just created a simple canvas with a button that shows App.ActiveScreen.Size as the Text property. Switched off Lock Orientation, Lock Aspect Ratio etc.
When I ran the app in Powerapps player (version 3.21054.24) on Android (Samsung S20+), switching from Portrait to Landscape mode gives a black screen, but I can see the landscape screen with the button if I scroll up 1 screen. It seems as if the portrait mode's App.Height was carried over to Landacape mode. I have not changed any of the default Screen widths and heights. I've also restarted the phone. This problem doesn't happen on an iPad with the same Powerapps Player version.
Has anyone else seen this? I've attached a screen recording in the link.
Screen recording black screen on rotate to landscape
Thanks in advance for the help!
