Did the issue resolve itself, or are you still not able to see new builds in TestFlight for internal testers?

Any luck, or still having the same problem?

I was able to resolve the issue in my case, by adding "App Uses Non-Exempt Encryption" to the Xcode project Info.plist I had been just clicking the 'manage compliance' link that would be shown by every build I uploaded, and that had always worked fine. As soon as I added the "App Uses Non-Exempt Encryption" key & value ('NO' in my case) to info.plist, the next build I uploaded to App Connect was delivered within a couple minutes to TestFlight.

Awesome, this is the way. PS - If editing plist.info directly the value for the key is the usual 'true' or 'false'.
