Paid apps when using 2 Google accounts on a same device?
I would test the theory first but I think they stay with the device after you sign off. You can also have two accounts signed on the same phone at the same time so your not logging in and out. You toggle them on all the google apps by clicking on your profile pic very much like the PC. If your good with file managing I have only had a few apps that I have paid for that I was not able to just import the file APK and actually share it with other user profiles and they worked just fine, in case you ever just wanted to have all paid on one account. Hope this helps some!
