User access to notebooks

[required_username 9]

I have EN Premium (I think).  I have 3 users on the account, just added the third.  I have shared a notebook with the 3rd user.  When he logs on through the EN app on a Windows PC, the Notebook appears.  When he logs in through his android phone, no notebook.  Just a note about being on a basic plan.  What are we doing wrong?  FWIW, all three of us log in using Google IDs.

We see a lot of posts from users logging in and not seeing notebooks/notes.
The usual cause is they're using the wrong userid and have accessed a different account.

Thanks for the response.  Let me start again.  I am the primary user.  I have shared a notebook with someone else.  He can access that notebook on a PC.  He can not access the notebook through android.  Gets a message "Upgrade to continue using EN on this device."  What next.

A completely different issue.  I'm guessing this is a user with a Basic account, that restricts to two simultaneous devices.
The user can access their account settings and revoke access to a non-active device.

Worked perfectly.  Thanks
