I have a tablet with Android 5.0.1.


I am the main User.


I have set up a Restricted User account (Settings > Users).


When I log into this account and open, for example, Google Play Books, it's showing all the books associated with the main User's Google ID.


This is a security issue.


I want the second account to be able to a separate Google ID associated with it.


From within this Restricted account, when I go to Settings > Accounts, I see no way to add a second Google ID specifically for this second user.


Any ideas?
