All of the automation rules I have created, have stopped. To test, I created a simple automation rule for when any issue transitions from Code Review to Ready for QA, a comment will be added.

Unfortunately, when I actually create a ticket, then make the above transitions, the automation is not triggered.

I checked the transition's post-function and it fires a Generic event.
I also checked the status site: https://jira-software.status.atlassian.com/ and nothing seems to be wrong.
I've created rules before, and they worked and not they have stopped. I am kind of at a loss here.
Please help!
