It’s both

Or just use ohook

Used this about 4 times in the past month alone lol

I do sometimes find stuff I wanna watch when browsing through YouTube though, and the uYou app is really good. Even allows me to stream up to 4K and screen off etc.

You don’t have to jailbreak, you just have to use AltStore and “renew” the app every 7 days. It’s a bit of a pain in the ass in all honesty but it’s still better than watching ads.

Or uYou on iOS

Or SmartTube on android TV
