We're building an iOS app in iOS 8 using Apple's version of TestFlight (integrated with iTunes Connect, of course). However, the system regularly refuses to send the "new build" notification e-mails to internal testers. In order to get build notification e-mails, I have to remove users from the internal testers group and re-invite them. Even when I have done this, the build notification e-mail (although it lists the desired version of the app) doesn't actually trigger an update in my TestFlight iOS app.
Points to note:
- I have the Connect and TestFlight apps installed on my phone.
- This has worked in the past with earlier versions of the app.
I have found other similar questions on Stack Overflow such as this and this one, but none of them seem to deal with the "this happens to me repeatedly" problem. Besides, most of them seem to suggest "remove all internal testers, disable beta testing on the app, then re-add them all" which is not a sustainable solution when we'd like to release multiple new builds per day through our continuous integration system.
Does anyone have any ideas?
ETA: I found an Apple Developer Forums thread on the subject. Not much help but it might be in future.
