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 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.
I had the same issue, Making changes to the "What to Test" field in the Build page and saving caused notifications to go out instantly for me.
When you upload a new build wait for a bit (I wait an hour) for all the processing to finish, then add the What to Test info and hit save. This seems to work for me quite well.
