how to free up storage? &brushes are disappearing from my Photoshop iPad every time I use it

Hello everyone!
I'm confused about how I am supposed to clear out some of my storage on my iCloud/creative cloud storage. I've deleted almost absolutely everything I have on files in all of my adobe apps and on the desktop. I've gone into the actual Creative Cloud on my laptop and the app and deleted a ton of things in there also but I'm still getting warnings that I have no storage left I don't know if that's affecting my Photoshop on the iPads ability to keep my brushes permanently because every time I go in and out of Photoshop on my iPad .....my brushes are gone. And I mean every time! It would be unrealistic for me to have to uninstall and reinstall Photoshop to get my brushes back seven+ times a day. Plus the problem of  not having any storage is an issue. I don't really use it for a lot because my I use external storage but the occasional file that I need to keep ..... I just can't do it right now nor have the solution to make it better! Any words of wisdom would be greatly appreciated! I

Thank you!
