TestFlight: Unable to Install App After Removing and Re-Adding Tester Access (Apple ID Mismatch Error)

Hello,

I am experiencing an issue with TestFlight that I have not been able to resolve.

Problem description

One day, I suddenly became unable to update our app from TestFlight using my tester account.

Assuming it might be a permission issue, I removed my tester access for the app and then re-invited the same Apple ID.

After doing this, the situation became worse: I can no longer install the app at all via TestFlight.

What I have already tried

I have attempted all of the following multiple times:

  • Removing and re-adding tester access in TestFlight
  • Deleting and reinstalling the TestFlight app
  • Installing the app via a new invitation link
  • Installing the app via an invitation code

None of these attempts worked.

Error message

Every attempt results in the same error message:

Unable to Load App This invitation is not associated with the Apple Account you’re currently signed in with (me [at] example [dot] com). Sign in to TestFlight with the original Apple Account (me [at] example [dot] com) or ask the developer for a new invitation.

Why this seems incorrect

The error message suggests that the Apple ID signed into TestFlight does not match the invited account. However, I am using the exact same Apple ID for:

  • TestFlight

  • Apple ID (device iCloud account)

  • App Store

There is no account mismatch. Everything is logged in with the same Apple ID (me [at] example [dot] com).

At this point, I am completely blocked and cannot proceed with testing or updates.

Question

  • Is there a known issue where removing and re-adding tester access can permanently invalidate an Apple ID for a specific TestFlight app?

  • Is there any way to reset or clear the tester state for an Apple ID on Apple’s side?

Any guidance or insight would be greatly appreciated. Thank you.
