Automated review didn't finish

The automated review process for https://dashboard.snapcraft.io/snaps/certbot-dns-dnsmadeeasy/revisions/822/ stalled for days. The snap was originally uploaded on June 16th and it was stuck in automated review until I manually canceled it on June 21st. Until I did that, the hung review blocked all subsequent uploads of this snap from being published.

Manually canceling the review resolved my immediate issue, but I'm not sure if the root cause of the automated reviewing hanging can or should be investigated and fixed. At the very least, I personally think adding a timeout to the automated review process would make sense. I'd be very surprised if the automated review here would have ever passed on its own.
