TestFlight builds are not being pushed to App Connect Users

I recently started having an issue with my TestFlight builds. In the past, if I built/distributed an app for TestFlight, the AppConnect group automatically received the builds and were able to install the on their devices. When I look in AppConnect, I can see the AC (AppConnect) group shown as a tester and that group shows the users I am expecting in them. The users are receiving an email from TestFlight saying the build is ready. However, when we go into TestFlight, it doesn't show the update being available for that new build.

What I have done as a work-around is added my AppConnect users to separate group and add them as testers each time I release a build to TestFlight.

Has anyone seen this or can they point out why this may be happening?
