I am actually debating canceling my yt premium sub over it and im going to twitch turbo, I have been progressively using yt less and less anyway and to be honest, the new price point (which was 13.99 for me) is not worth the benefits it provides. mobile queuing can be used via playlist or watch later, adverts are annoying but avoidable with new found apps approaching. Downloading for offline use is a joke, it barely has ever worked for me. Picture in Picture mode is buggy and for the most part I don't use it. This combined with the absolute crap recommendation system they have had the last few years(like seriously its all either stuff in my watch history or stuff that is unrelated to anything I watch). I'm sure they are just following every other company but, it might just push me off lol
Also to clarify your nuking account thing. I expect you signed up via either apple subscriptions or google play subs, both of which take a chunk out of the money given. So that might be what is going on with the price diff.
It's not just the tab s8, I have a tab s7 and it's super bright and obnoxiously loud even at the lowest settings. I don't understand why there is not more control over it.
