I don't know the answers to your questions about how much space the app (or an average drawing) should take up on your device, so I've dropped a note to the product team.
I'll post as soon as I hear back from someone.
Awesome. It's an android device, and I'm sure it's far from the most optimal, but all the same, it seems odd that one drawing is taking up over 4 gigs of storage. Thank you thank you!
Definitely. The app takes up only 56mb on my iPhone. This hogging of storage does happen once in awhile (on both iOS and Android) and an uninstall/reinstall of the app usually resolves it. Have you tried that?
If you haven't tried it yet, before you do, make sure that any work you want to keep is synced to Creative Cloud. Log in with your Adobe ID to Adobe Creative Cloud and make sure all the work you want to keep is showing up there. Once you see that it is, go ahead uninstall.
Thanks a lot. Trying it now. I'll let you know if there's any progress. It'll probably take a bit of time though, since I didn't run into any issues until I put some artwork on there (even though it wasn't much)
