It's now been a few months since I started creating PowerApps. And I like the tool a lot. However there seems to be a very annoying bug I've experienced several times in the last few weeks.
I'm making some advanced settings in the pane on the right side. There I mark some code and want to delete it. But before I can hit the delete button, the cursor jumps back to the main area somehow. As a result I delete a whole form by mistake instead of deleting just the marked code.
Of course there is an Undo button. But several times that didn't restore my form properly. Instead fields where moved around and formats like reset to standard.
Luckily I could save most of my work by restoring the previous app version. But I had to do that already twice today. Quite annoying really. Therefore I decided to enter the bug into that forum.
