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!

TestFlight is currently unavailable. Please try again later.
