Since Apple moved to their new and improved TestFlight website, none of my internal or external users are receiving push notifications or emails when I make a new build available for testing.
These are testers who previously were getting push and emails with each new build.
If the tester goes to the TestFlight app on their device, they do see the new build is available for update there.
I see a couple threads about this in the Apple Developer forums but nobody seems to know how to work around this problem:

Anyone here found a workaround for this problem?
