Testflight not working on iOS 11 beta

I had the same issue, it got solved by reinstalling the TestFlight app from the App Store. Good luck! 🙂

Thanks ... didn't work for me. I get a "testflight unavailable" error.

I’m having the same issue on the public beta 1. I tried deleting it, hard reset & reinstalling. No luck so far. Might try to clear cache in the App Store this next time. It’s not a good thing for me as I’m involved in about 20+ beta’s. Many of which are for higher profile indie Devs. So far this is my only regret for updating.

Did anyone find a solution to this? I am having the same issue. "TestFlight Unavaiable"

Same for me. No solution found

I'm having the same problem. I've got the beta installed on both my iphone and my ipad. My ipad has remained logged in to testflight so it's been ok. My iphone somehow got logged out around the time I upgraded and I haven't been able to get back in. Does anyone have a sense as to whether this is an issue with the os beta or the upgraded two-factor authentication?

I have the same problem on ios11 public beta.

I was getting a ‘not available’ error when I tried to login with my primary Apple ID.

REinstalling the app, restarting device did not work.

i Was able to solve it using my secondary Apple ID that uses @me.com rather then @gmail.com email.

it is pain to ask all the developers to reassign my Apple ID for a secondary one, but the only solution I found.

it is imperative for developers to test their apps for upcoming iOS 11 release, and I am not sure why Apple did not fix this problem yet.

good luck,

I have Got this problem and finally get it fixed. Rest all Settings and enter your App Store password before going to TestFlight. After that, no need to sign in to TestFlight and no more “temporary unavailable“ message.

I'm getting the same. Have tried:

1. Resetting all settings on iPhone
2. Reinstalling TestFlight.app
3. Logging in with @me account

Nothing works.

Tried @me.com and it didn't work for me.

Tried resetting all settings, the problem persists. Anybody else got this solved the same way?
