TestFlight is currently unavailable. Please try again later.

While testing a new iOS build for Tap In Guide I started getting this error when trying to open the app from TestFlight on my phone “TestFlight is currently unavailable. Please try again later.”

After trying again and again and again I still wasn’t able to open the new build — or any build — in TestFlight. I looked over Stack Overflow and the rest of the Internet for suggestions and a lot of people were having the same issue but with quite a few different solutions.

These are some of the ways people have fixed or gotten around the error “TestFlight is currently unavailable. Please try again later.” .

My solution

  • Remove myself from Testers (iTunes Connect → Your App → TestFlight → iTunes Connect Users → Testers → click the red circle on the line with your user.
  • Readded myself as an Tester (Make sure “send notification” is checked).
  • Open the TestFlight invite email notification from my phone.
  • Click “View in TestFlight” button from the email.
  • Done. This should open TestFlight on your phone and give you the option to install the new build.

Other solutions

Those are all the different ways to fix the error that I tried and have worked for other people. If you fix this issue using another method, please let me know and I’ll add it to this list.

Good luck!
