In Apple Music’s For You section, there is a My Favorites mix; or a My Favourites mix. Actually, there’s both. The icon for the playlist uses the US spelling, and the name uses the UK spelling. (Yes I’m in the UK, but I’m seeing this with a US account; people in the US reported this as well.)
Is this just an oversight? Or is it similar to having Jony Ive say “aluminium” in Apple’s product manufacturing videos?
