I uploaded my app to App Store Connect to test it through TestFlight. Initially, I was able to download, install, and test the app without any issues. However, the following day, the app was no longer visible in TestFlight, and I could no longer download or install it. It has now been three days, and the issue still persists. I have been unable to access or reinstall the app through TestFlight. Could you please help me understand why this happened and how I can resolve the issue? Thank you for your assistance.
