TestFlight Internal Tester Invitation Emails Are Not Being Delivered

For approximately one week, we have been unable to send TestFlight internal testing invitations.

Invited users appear with the status "Invited", but no invitation date is displayed, and no emails are received.

We have already tried recreating groups, resending invitations, using Safari, uploading different builds, and inviting users individually.

All email addresses, user roles, and account requirements are correct.

Interestingly, we also tested the same process using another developer's App Store Connect account, and invitations were delivered successfully. The issue only occurs with our account.

Hi there,

Thanks for flagging this. Can we please get a Feedback Assistant ticket filed so we can look at this more closely?In the ticket, it would be good to get the following:

  • Detailed steps to reproduce
  • Screen recording and screenshots
  • HAR logs

To get the .har file:

Open Safari.
Choose Develop > Show Web Inspector. The Inspector menu appears at the bottom of the window.
Click the Network tab, and then click the XHR/Fetch tab.
Click the Preserve Log checkbox to select it.
Reload the page to replicate the issue.
Click the Export button.

Please post your ticket number and we'll be happy to investiagte this.
