i pay for premium. But funny thing, this will not disable the tracking, so I still use the ublock. I've also had problems when visiting my parents in another country and background play was blocked bc yt premium was not available there, even if i was a paying customer. At that time I was using yt in firefox mobile with background play. I also still get sponsored ads and need to use the sponsorblock extension, that does not work for yt mobile app. In other words paying premium solves a small subset of problems and gives a worse experience compared to ppl that use ublock+sponsorblock in the browser
