ios – TestFlight exhibits app however set up fails with “The requested app isn’t obtainable or doesn’t exist”

I’m dealing with a TestFlight inside testing difficulty and I’m attempting to know whether or not that is an Apple-side distribution drawback.

Present state of affairs:

• Construct is absolutely processed

• Construct standing is Testing

• Inner testing is enabled

• Testers obtain the invitation electronic mail accurately

• Testers can open the invite and see the app in TestFlight

Downside:

When urgent Set up, TestFlight exhibits:

“The requested app isn’t obtainable or doesn’t exist.”

The set up by no means begins.

What I already tried:

• Eliminated and re-added testers

• Despatched recent invitation emails

• Created new inside testing teams

• Reassigned the construct to recent teams

• Examined with completely different Apple IDs

• Reinstalled TestFlight

• Restarted the machine

• Opened recent invite hyperlinks

• Verified the Apple ID matches the invitation

• Verified the construct is energetic and assigned accurately

System information:

Vital:

The app seems accurately in TestFlight.
Solely the set up step fails.

Questions:

1. Has anybody seen this precise habits?

2. Might this be an Apple CDN propagation difficulty?

3. Might inside tester entitlements be corrupted?

4. Is there any hidden motive a construct may be seen however nonetheless not installable?

Attempting to know if that is one thing on my facet or a TestFlight infrastructure difficulty.
