Problem with latest update in the App Store?

This may only be a problem for me, but I’ve noticed it on multiple ATVs so I thought I’d let you know.

Clicking on the Channels app doesn’t start it. When I attempt to reboot my ATV, an error message appears stating ‘Could not install Channels app’.

I deleted the app and attempted to reinstall from the App Store, and got the same error.

I was able to install the beta version from TestFlight with no issues.

how did you install with testflight? did you received the redeem code from them?
