Last week, my app stoped to work correctly. When I press "Play" in powerapps studio, I can't press any button, the fills of the button and labels return black and they don't make their functions. In addition, screens have moved all their labels, forms and icons. I have tried to open my app with other computers, and I have open lots of previous versions to see If the problem is something that I did last friday, but it doesn't woks neither. What can I do to solve it? Has it been an update problem?
