@MartinSleziak Sorry, I forgot to ping you. Please check out the message above.

@YuiToCheng The question seems to be still in the review queue: math.stackexchange.com/review/close/1340389

Review appears in the timeline once the review is finished.

BTW your question would be a reasonable fit for Math Meta chat.

Maybe I should have mentioned that I found the close review using filter by tag in the close votes review queue.

@MartinSleziak Thanks. Do you know of any reason why the post is still stuck in the review queue?

Now that the review was completed, you can see it in the timeline and in the revision history.

@YuiToCheng I think that the answer is relatively obvious: Many questions in the review queues, not enough users reviewing.

I think I had a SEDE query somewhere which showed times needed for reviews.

@YuiToCheng I do not know. You can try to ask in Math Meta Chat (maybe somebody else will know more about this).

Or if you prefer, you can try to ask in Tavern on Meta.

You can also try to search a bit on Mathematics Meta, to see whether you can find the answer to this question there.

@MartinSleziak Ok. Thanks for your quick reply.
