I’ve noticed a strange bug where, if I’m writing quickly, pressing the eraser button will bug the whole app out. It seems to always be just after I try to switch to the erasing tool with the eraser button on the pen, but that could just be when I end up noticing it.
Unexpected behavior includes not being able to erase, the buttons on the side not expecting input, etc. It kinda renders a lot of the app unusable, and it happens so frequently to me that I’ve developed muscle memory for noticing it and immediately triple tapping the home button to force my way out of the notes app so I can restart.
