TestFlight Could not Install app

I am trying to invite internal testers but Testflight keeps rejecting them from downloading with a pop up that states "The requested app is not available or doesnt exist" it does say on App store connect that it is Complete as far as to begin testing. Any one have any suggestions? I am new at this. Thank you.

Thank you for your post. I would like to request two favors from you. First, could you create a bug report and provide me with the Facebook number? Second, could you add yourself to this thread and monitor it? https://developer.apple.com/forums/thread/773818

Once you open the bug report, please post the FB number here for my reference.

If you have any questions about filing a bug report, take a look at Bug Reporting: How and Why?

Thanks again for everything. Looking forward working with you to resolve it quickly.
