AppleTV Plus App Will Not Launch On X1

I've tried a dozen times or so over the past several weeks and the AppleTV+ app on the X1 platform fails to launch.  It seems to get stuck on the display showing a black screen with the apple emblem with tv+ forever.

All other apps work on X1 including Peacock, Disney+, Netflix, Prime Video, Hulu, Youtube, HBO Max, Paramount+, etc without issue as expected.

Also as expected, I'm able to access AppleTV+ on my Apple TV streaming box, FireTV box, TCL Roku TV & onn. Google TV box.

I have tried rebooting the X1 cable TV box.  I have also tried launching the AppleTV+ app on X1 on one of my other X1 boxes and it fails and sticks on the same screen.  Not that it should make any difference with the app launching but I do have an active Apple subscription to AppleTV+ via directly thru Apple.

I thank you for your attention.  This is a relatively low priority problem as I have the other platforms to access AppleTV+ but it would be nice to get this fixed.
