Is there any way to create some kind of shared folder that all user profiles have access to? I read that there used to be a folder in /android/obb that was used for this exact purpose and I actually found it in my system, but it appears that this directory no longer works as expected.
I think a possible solution would be setting up Syncthing on both profiles, but, from what I understand, that would create a copy of every file I create, wasting a lot of space.
