Ive been using https://invidio.us and https://invidious.snopyta.org as YouTube alternatives and honestly im very pleased. Unlike NewPipe, the subscription feeds actually show the newest videos you're subscribed to first just like YouTube does. I was able to import all my subscriptions.

They use googlevideo to provide the content (which is sketchy since that is a huge tracking issue), but there is a setting to enable proxy video, which I haven't fully tested for privacy.

Also a dark theme :D
