More than 12 hours ago, I tried to create a tag wiki for the poker-face tag but encountered an error message:
The edit queue is full at the moment - try again in a few minutes!
I tried again in a few minutes but got the same error message. I checked the suggested edits review queue and found out that it's clear - with nothing to review, unlike what the error message says. I assumed it was a temporary issue.
More than 12 hours later, I tried to create the tag wiki again but got the same error message, and the suggested edits review queue remains clear.
Update: A day later, the issue still persists.
