Grinding got worse???

I don’t know if anyone else is having this issue but this update messed up grinding I normally have my assist down to 20 before update and have no problem locking in to where I want to be and now with this update grinding is way different it wants to throw me into a whole different rail or wall that’s next to what I’m going for then I turned up assist to 100 and it’s still exact same I can’t get through one challenge without smacking into something and failing and same with getting up to a high ledge to grind just decides not to jump high and smack the side of the wall and I know if you hold up it jumps higher. Like what is this
