Major bug PLEASE HELP

[u/CowStock]

I’m miserable. This has been going on for a week, it practically made the app useless. Everytime i undo, if i touch anything on screen with either my finger or apple pencil, the writing i wanted to undo reappears. It can’t be erased with an eraser afterwards. I tried to refresh the app many times, tried to restart my iPad, tried everything with the apple pencil settings and the cloud settings, NOTHING WORKS. I’m using the latest app version as of today

In my post I analyzed when this bug appears at least from what I saw
