When I click on the review queue button, it shows
There are no review queues available to you
I previously had access and I am wondering if this is just saying that there are no queues that need to be reviewed or if it's a bug?
I think it may be caused by having used up all your up/down votes for the day—you've cast 40. See here: Review queues seem to have disappeared
So it's not exactly a bug, but it certainly isn't an ideal user experience.
You have enough reputation for the Access Review Queues privilege (500+) which means you should be able to see the Late Answers and First Posts review queue otherwise. You are also not review banned which caused this issue for someone else.
