I have Photoshop 2020 installed and I have not been able to figure out an eraser issue. Usually when I have the opacity lower than 100%, I can gradually erase a spot by going over it multiple times until it eventually is gone. Now, when I have the eraser lower than 100%, no matter how many times I go over a spot, it only erases a certain amount of the image and I have to keep clicking in order for it to erase completely. I do a lot of composites and it is impossible to get a nice, clear cut-out with this feature on. I have tried to turn on airbrush and have messed with smoothness but nothing is working. Please let me know if there is an easy fix for this extremely annoying issue.
