This is a common problem when queuing into any Cyrodiil campaign that has an active queue: Your queue position will often become "frozen" and fail to advance.
There's usually no indication of this problem, so the only way to tell if if you have a friend also in the same queue whose position is advancing while yours remains unchanged. Reloading UI (and disabling addons) has no effect. The only way to resolve it is to leave queue and queue again, which means essentially starting over at the back of the line regardless of how long you were previously in queue. In some cases, this will happen after having been queued for half an hour or more.
Is there any timeline for looking into this issue?
