Release Date

29th March 2021

Overview

If users have the Access Control integration enabled, in the Users -> Roles dialog, there's a toggle called 'All permissions' that allows users to provide or revoke all access control permissions to specific roles.

Changing it and clicking 'Done' doesn't actually update the underlying role due to a user interface bug, and the user is not informed about the failure either. This also means if the 'All permissions' toggle has been turned on, it is not possible to turn it off to revoke permissions through the Ava Aware user interface.
