NewPipe does not have cast functionality and doesn’t include Sponsorblock.

Revanced is complicated because you first need to find a compatible YouTube version (old version) and download it’s APK. Then, you need to uninstall YouTube, apply Revanced to the downloaded APK and then install it Only to discover the Cast button was removed by Revanced. When you start over, deselect “remove cast button from video player”, you still end up without it.

I can’t even cast to SmartTubeNext on AndroidTV…

Way too complex and too limiting for 99.99% of YouTube watchers.
