I've had this issue only on the newest version of the game. The controls occasionally stop registering my finger after I've pushed either tilt or speed. So after I've done a backflip and landed, the vehicle starts slowing down. Or the vehicle doesn't start to flip at all unless I press the button again. I'm not sure if this is something that anyone else sees.
Device: Samsung S7 Edge.
It's really frustrating. On multiple occasions I've lost couple of runs when trying to complete, and I'm not even nearly good enough to win on the first solid try. The bug also eats a lot of nitros obviously.
