I use Clipious, an Android client for Invidious, on my phone. I selfhost my own Indivious instance so this is perfect in that my phone never connects to YouTube directly, and I can save all my subscriptions in one place without a YouTube account.
On my Android TV I use Smart Tube Next. If I really need to cast, I also have YouTube ReVanced on my phone for just that, but I barely use it.
As soon as Clipious gets a proper Android TV interface, I’ll be set, as both devices can just connect to Invidious and let it do all the work.
Atheist here. Extraordinary claims require extraordinary evidence. Atheism is merely about trusting what’s been proven, or has some evidence backing the claim that can be verified without doubt. Being agnostic is being indecisive about everything, even things that are completely made up.
