Same issues. "Your Beta is expired" error...then we delete the app, then Install death spiral where it keeps trying to install but never works. Apple has indicated there is a performance issue with Testflight but when will we get an update?! https://developer.apple.com/system-status/ Adding to this thread in hopes that volume of complaints will help prioritize a fix on their end. We were about to ship a big release to our testers! Come on Apple!

I see on Apple's System Status page that they say they have resolved and performance is now back to a Green Light. But the problem hasn't fixed for us. Is it working yet for anyone else?
