Give it time and you'll get used to it I'm sure.
As an old player (12 years) I don't find it hideous, yes it looks a bit square peg/round hole and a touch on the clunky side but I've seen worse updates.
There should still be an option to chose which style of map you can view because it seems this map is to make things easier on the mobile app - Many don't play on the app, give us a choice as to which map we view perhaps?
