Why mobile (jump) button not jumping while running

OK will try it out. How ever I found out with default mobile doual buttons that if I hold jump for one second then next time I’m running it works. So as longs as it has been held for a sec then when your start running it’s working fine. As it if it has a bit of delay to turn on first. Gonna play with settings to see what came of it. Let you know what happen>
