starting a day or two ago, sometimes my powerapps screen becomes completely blank (not the white canvas) when I navigate between screens and I cannot seem to figure out why. This happens even when I am editing the powerapps and it seems to work for a tiny bit when I refresh the page but breaks soon after. It seems like the objects are still there in the navigation but is just not visible. This happens in the published version of the app as well.
I've been having the same, just been saving, closing and then re-opening.
To do with new rendering perhaps?
Happening 5+ times per day now. Only an inconvenience, but still unwanted!
Trying the different methods you talk about here I was unable to fix my problem, even after exporting and creating a new app with the export. In my opinion there is something broken with what I added to the latest versions...
Will keep you guys posted if any thing changes.
