I have developed a mobile application in flutter and I want to ship this application to test flight for testing. Everything has worked fine. I created a group for internal testers and invited them for testing but none of them is getting invitation for testing on test flight. What should I do? I have exhausted all the solutions available online and none of them is working for me.
I have tried adding and removing users over and over again and re-sending the invitations. The dashboard of test flights says that the invitaions has been sent, but no email received. What could be the potential reason for this behavior.
I was able to resolve the issue. I added capabilities like Push Notifications and Apple Sign-in in Xcode as well as in the Identifier tab of Apple Developer Account. When I re-signed the app with the updated provisioning profile and with updated capabilities in Xcode, the invitation emails were sent immediately.
