Once ticking swap jump and sneak in settings, you were able to hold the move forward button and simply swipe towards the centre of the d pad to jump and then slide your finger back up to the move forward button. This could be repeated as many times as desired. Since a recent update, swiping down still works the first time, but the button stays pushed down until you completely remove your finger from the screen. It is very frustrating as someone who doesn't use auto jump because I need to keep taking my finger off the screen after a single jump if I wish to jump again and I lose all forward momentum.
