I prefer my zoom settings to be "press" and not "hold" for all weapons. Previous to the most recent update I could "press" to stay zoomed as the tank driver aiming the main cannon and on the stationary AA guns. Now you have to hold the trigger to zoom as the tank driver and on the stationary AA guns. I have the vehicle zoom set to "press" and I've also tried toggling between "press" and "hold" to see if it was just a temporary problem but it doesn't appear to be. The "press" setting works for all other seats in the tank, just not for the tank driver. I don't know if this was intentional but either way it is disappointing.
