Some times manual controls with sliders won't work (Reverser, throtal and brakes). The one that you just push X work (horn). I have to go to main menu then back into session to get them to work. Bottom on controller still work.
I'm having the same issue so much so that the game is unplayable!!! If I'd have bought a physical copy it'd be going straight back to the shop!!! To say I'm pissed off is an understatement
