Hi Everyone, I am having a major issue with the Apple Test Flight application. When I reinstall the application while signed into my Apple ID and try to hit “Continue” at the bottom of the introductory page I get the following error message and am unable to proceed further to access all of my registered Test Flight betas: “ TestFlight Unavailable Device vendor ID is missing or not available. Try again. “ I have an iPhone 13 Pro Max running on iOS 16.4.1 (a) Please let me know what to do to fix this issue so that I can continue using Apple TestFlight again and help developers test their applications. Thank-you, Shawn

Hello everyone, I am no longer to access all of my TestFlight betas. I tried contacting Apple Support but they have not helped me with the situation. This message only started occurring a few days ago. I am running iOS 16.4.1 Message: TestFlight Unavailable Device vendor ID is missing or not available. Try again. Steps taken: -Deleted and re-installed Testflight App -Restarted iPhone 13 Pro Max Screenshot at imgur link below https://imgur.com/a/DJZJ5Y0 Any help would be appreciated to get TestFlight back up and running Thank-you, Shawn Osborne
