I thought apps are fully sandboxed and users fully isolated, and even if I try to install it on a second user there seem to be some kind of communication in between. Am I doing something wrong ?
Main user no apps installed.
Second user install ProtonVPN directly from official source and set it up. All good!
Main user downloads f-droid and tries to install ProtonVPN but fails because of error "Failed to install due to an unknown error".
Replace ProtonVPN with any other apps tested, such as Tutanota mail client and same issue appears.
If I do the opposite, and install lets say Tutanota f-droid version on Main user
Second user I try install official version from github I get error "can not install app package conflicts with an existing package"
The only way I can install the app on second user is by uninstalling it in first. And make sure I have same signed app installed on both users.
Is this by design or an existing issue?
