I'm thinking of installing sandboxed Play Services in a work profile rather than second user. This is for convenience reasons such as having full notifications including content, being able to transfer files via Shelter's file shuttle, being able to copy/paste between apps of different profiles and all that.
Can apps in the main profile see what's installed in the work profile?
For example when you install Signal it will check whether Play Services are installed. Would it be able to detect the Play Services in the work profile, or is that completely separated similar to a second user profile?
