Bump the build number and resubmit your app. This is a TestFlight/iTunes Connect-side error that, as far as I can tell, we can do nothing about.

Update 12/7: The bug I filed on this (rdar://23296795) was recently returned to me as "We believe this issue has been addressed through changes on our side." – So if you're still seeing this error, please file another radar and let them know it's still not working.

Update 12/10: According to Remy in the comments below, it is still not fixed.

I faced the same issue under the follow case: Created a Test users group in iTunes Connect even before the Build was approved (i.e. it was in "Waiting for Review" state). We did receive notifications from TestFlight, but when clicked on "View in TestFlight", received this error. I added the approved build to the Group and Resent the invites. This worked perfect for me.

We had a user who had, for reasons only they know, disabled cellular access for the Testflight app. Later, when he'd also turned off Wifi (again, for reasons...) he was in a situation where Testflight had no connectivity.

The error he saw was "could not load apps". It was driving us crazy as our other users were able to install and run without issue!

Answer 5

Same error for me. The only thing that worked for me was to uninstall the TestFlight app and then reinstalling.
