We had an issue before this where:
1. We upload the app to iTunes Connect. (We can then see it under TestFlight and iOS builds)
2. We click Provide Export Compliance (As we cannot test without providing this information)
3. Received an error (Something like "Please try again later")
We can now get past this but have a new issue.
The issue:
1. We upload the app to iTunes Connect. (We can then see it under TestFlight and iOS builds)
2. We click Provide Export Compliance (As we cannot test without providing this information)
3. We choose "nothing has changed/app has no encryption"
4. We click "Start internal testing"
5. Go back and the app has disappeared from builds. The version numbers stay, but there is nothing under them.
