If you keep getting an error message whenever you try to do anything in iPaper, it might simply be because the system has logged you out. This could be either due to inactivity or a system update being deployed.
In this case, a simple solution is to log out and log back in again:
Click on the Account name in the top, right-hand corner.
From the drop-down menu, select Sign out.
If that does not solve the issue, please contact us via the chat in the corner, or email us and we'll be happy to help! 😃
