Same issue here. It started about 24 hours ago and I haven’t found a solution yet.
Things I have already tried:
• Rebuilding the app multiple times via GitHub Actions
• Regenerating certificates / Match secrets
• Waiting 24 hours after upload
• Deleting the app and reinstalling
• Deleting and reinstalling TestFlight
• Restarting the phone multiple times
• Verified I’m assigned to the internal tester group in App Store Connect
• Confirmed the build status is Complete in App Store Connect
The build installs and runs on my phone, but when I open the app page in TestFlight it shows “Couldn’t Load App – TestFlight is currently unavailable.”
Also noticing the Apple Watch companion app will not install (stuck installing).
