LG TV unstable with 3rd Gen Apple TV 4K since tvOS 16.3.1 (20K661)

Hello -

We need some recommendations for using our new Apple TV 4K (3rd Gen). There is a "no connection" when moving between Apps (Netflix, Prime, etc.) and between individual show episode. Didn't have this happen before latest update to tvOS 13.3.1 and never with our 2nd Gen Apple TV 4K.

Any recommendations would be greatly appreciated.

Thank you for your assistance.
