X1 Streaming Apps on XG1v4 Experience Degrading

I have enjoyed having my entire TV experience integrated into the X1 Interface / Guide. However, in recent months the streaming apps on the X1 continue to degrade. Not sure why recent updates or lack of updates continue to make the most mainstream apps function poorly. 

• Paramount + - No longer supports 5.1 Surround Sound and lacks 4k content. 
• YouTube - No longer supports 5.1 Surround. 
• HBO Max - Constant performance issues and stuttering. Supports Dolby Surround. 
• Netflix - Red loading circle when selecting shows from the X1 guide. Works fine if you just launch the all and select the snow directly. Supports Dolby Surround. 

Peacock, Disney+, and Apple TV are the only apps left that function flawlessly. 

Hoping Xfinity can correct these issues so customers can have a seamless TV experience again. As of now, I am slowly just using apps on my Smart Google TV and they work fine. However, not having all your entertainment on one platform is frustrating.
