This had been happening for my iPad Pro for a while now, but I just thought it was because I was storing everything on the ipad & not icloud. When I noticed I was running out of space, I too removed everything from the iPad and moved all to the cloud. Nope, didn’t do anything, and it’s creeping up to almost taking up all space as well now. How can this have been a problem for so many for going on 2-3 years and nobody has a solution. I LOVE AD & AP and left Adobe & their lacklustre iPad “Pro” apps for them with no regrets, but HOW is this still happening with NO fix?!? I don’t want to simply “delete & reinstall” every time this happens - I have settings & brushes etc etc that I don’t want to have to reinstall.
Very frustrating!
