When I add a new build of my app to App Store Connect and. then send it through internal testers testflight will not send that new version of the app to the testers, it will only. send an older version.
Please note that the new version is labeled as testing.
thanks in advanced.
A couple. of threads about this.
Currently Apple's status page still shows an issue with the TestFlight service, but no explanation and no ETA as to when it will be fully resolved.
