This plugin works wonderfully except for one thing - after I've assigned a user to a certain group, it will "stick" for a while until UAM (without any prompting from an administrator) removes the user from that group. This happens within a matter of hours and affects some users but not others.
This is a deal-breaker because users' access to their group pages is unpredictable and not at all guaranteed. It would be incredibly inefficient and ineffective for administrators to check manually if their users' group memberships were still intact. Does anyone have any suggestions for fixing this?
