Recently, my Artstudio Pro files is not appearing as thumbnail previews in Gallery view or even the Files app. I'm wondering if anyone has faced this issue and solved it. My Artstudio Pro is the latest with iPadOS 16.3 on an M1 iPad Pro.

I've tried:
- Restarting the iPad
- Hard restarting the iPad
- Deleting and reinstalling Files app
- Deleting and reinstalling Artstudio Pro

Not having the previews is just a big turnoff, and times like this I wish it wasn't linked to the clunky and buggy Files app. I prefer the original gallery view with iCloud backup support, but that's just my opinion.

Anyway, if anyone has ever came across this same problem, and found a solution. Please share.
