Thanks for the logs.
Apple TV seems to be DRM releated issue. It also seems that there is no regular mobile version of Apple TV app available. Android TV versions usually have more restrictions on device certification (e.g. regular mobile Netflix works while the Android TV version doesn't).
With a quick glance not sure what's up with Paramount Plus. There seems to be one native library missing (libbrotli_native.so) that is gapps related. Likely unrelated if it's only choppy playback/buffering you're experiencing.
