How to enable this?

Try to go to Galaxy Store and search Samsung My Files. I think there's an option there.

Samsung My Files is working, but the built-in files app is disabled. I can't upload files in drive.

To everyone who experienced this issue, it can be fixed by tapping the Reset app preferences.
