After some time of inactivity CCPv2 throws the error below and redirects to login page despite the session should still be active:
We're sorry, but something went wrong. Please, contact your support team for assistance.
The error is taking place when APS token (which is hardcoded to 30 minutes) expires earlier than the session.
The behavior will be fixed in the scope of software issue #APS-40247. The fix is planned to be included in on e of the future product updates.
Contact your Technical Account Manager of PTA team (firstname.lastname@example.org) to trace the status of the issue.
Consider settings session timeout less or equal to 30 minutes as a workaround
