I HATE Short form video content and no matter how many times I select "show me less of this" I still get them front and center when I open the app or website.
I hate that 'feature' so much.
Is it because I'm signed in to youtube, maybe?
The setting propagates to other browsers signed in to the same account, I think.
Maybe part of the issue is that I am logged into the same account across three different devices, or that I have other Google accounts too logged in (but I don't use YouTube in them, only the account with Premium).
Anyway, it should be trivial for Google to make it actually permanent (I would love it it was stored in my account, which I pay for Premium on, instead of local or cookie storage), but lots of people have this problem.
