Gossygos I currently use the owner profile for my main daily usage (texting, calling, email) and use the private space in the owner profile for my banking and social media apps. I like this setup because I can limit my use of social media and the notifications by locking it, and it allows me to share the clipboard when logging into banking apps. It find it more convenient but still isolated to an extent.
I'm working on setting up other user profiles again to isolate things more and have more specific uses for them, but still working on that as it's tricky to get the right balance of convenience and compartmentalization.
When I first started using GOS I tried isolating everything in different profiles and it was too much lol. So I've just been daily driving using the owner until I get a feel for my needs and build out from there.
