I'm the account holder I've using test flight a long ago, but today I faced this problem for my forst time
The group is there but inactive ?!
TestFlight I can't add internal testing group to my recent build
This issue starting happening to me today as well. Created a new internal beta group, added myself to it, and was able to assign that group to the new build. However, build does not show up in TestFlight and it has been about 5-6 hrs.
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.
Same here. Thank you for sharing.
