Kinda odd that even with the Song of the Welkin Moon "rebrand", Genshin still hasn't changed their banner thumbnail for their Youtube's gaming category. Heck, they even changed the Playstation's banner after many years

Not like this is like impossible to change, since popular games like Forknife and Call of Duty usually change the banner thumbnail with each new season. i figure Hoyo can do the same with Genshin except change banner for each new region.
