For some reason I am not able to use the control/option brush shortcut anymore to control the brush size and hardness. I am running Photoshop CC 2017.1.1. I am using a Wacom as well and have tried using the old driver and the latest driver to see if either one would help with this issue and no luck. The keyboard is working fine as well, I have even tried two other keyboards and still nothing. Has anyone had this issue recently and found any solutions? It has really affected my workflow 😞
