Builds suddenly not showing in TestFlight

Is anyone else suddenly having issues getting new builds to TestFlight?

It worked earlier this afternoon and I pushed build 22 of my app. I found an issue, made a fix and expired it. Then I built and uploaded build 23 about 45 minutes later and now that one isn't showing 90 minutes later. I didn't make any other changes to my project, just a simple 2 line fix. I'm doing the archive and distribute the same as I always have and am seeing no errors, nor am I getting any error emails.

Could pushing 2 builds within an hour put me at the back of a queue, or expiring my latest build before uploading a new one caused an issue?

All builds up until now have shown within minutes.
