Struggling with getting access to testflight

I’m running into an issue with TestFlight and would appreciate any help or insight.

A developer previously sent a TestFlight invite to my email address, which I accessed on a different iPhone (my girlfriend’s), as I was using a non-iOS device at the time. The app installed and worked fine on that device.

Now that I have my own iPhone and have downloaded the TestFlight app, I can’t access the invite or app under my own Apple ID. The developer has tried to resend the invite to the same email, but I’m not receiving anything — no email, no app showing in TestFlight.

We also tried:

  • Reopening the original invite email on my new iPhone
  • Reinstalling TestFlight
  • Checking for any spam/junk mail
  • Confirming the correct Apple ID is used

Nothing has worked so far. Is there a way to:

  • Reset or revoke my original TestFlight tester status?
  • Ensure a fresh invite can be sent and received?
  • Link the original invite to my current Apple ID and device?

Appreciate any advice — thanks in advance
