I use a controller. I have some serious injuries to my hand, and it means that I'm not very nimble with a keyboard/mouse setup. Using a regular Xbox Controller, I have noticed a few problems. While ADSing, I cannot click the Right Analog stick to left right without also activating my Optic Zoom. If I use an optic without any zoom function, this isn't a problem. I believe the problem is that Lean Right and Optic Zoom are bound to the same button, but this wasn't a problem before the recent update.
Another problem is that Crouch is set to hold, not toggle. This means that I can no longer tap the button to crouch, because as soon as I let go I stand back up. If I hold the button, I go from crouch to prone (the way I'm supposed to). Effectively, this means I can no longer crouch.
Can you set it back to how it was? Or add in the option to edit your own layout on controllers? I effectively can't play the game anymore.
