Even though I clean my history (line by line for hours), I am unable to change favorite songs and recommended playlists. My recent listenings barely added and keeps playing same songs that I used to listen. This makes the app very dull. When I open to listen a music but I immediately close after seeing same things. Since it's connected to my usual youtube account, clearing the entine history would make things even worse. I can't switch another account because only one instance holds the premium.
