Having the same issues. Queued for over an hour on Levelling Roulette earlier before I had to drop.

Currently queueing over 45mins again. Something definitely not right. And again showing 0 dps queued even though I'm one of them.

I wouldn't mind if someone I'm SE gave a response to say 'yes it's broken, we'll have to look for a way to fix but could be a while' or explain why queues have gone over the hr mark from taking 10-15mins max before 3.1 but the current Dev post is a bit inane
