I recently discovered SmartTube Next for Android TV to get an ad free experience and integrated Sponsorblock on my Nvidia Shield TV.
I found NewPipe for my phone but I don’t see a way to connect my YouTube account to it and I guess I need to import my subs manually every time I change something.
So I’m wondering if there is an alternative YouTube app that is blocking ads (and ideally integrates Sponsorblock) for my smartphone and has the ability to connect my YouTube account like SmartTube Next does?
Have you tried the Grayjay app https://grayjay.app/ although it encourages you to not block ads and sponsors for the benefit of the creators you can in the settings. It also allows you to connect with your various accounts, YouTube and others.
