Spot healing brush not working
I am using 21.1.2 version and the brush isn't working. There is a stack of paper icon in the options bar, but nothing happens when I click on it. I presume that is the sample all layers button and that this is the reason the spot healing brush doesn't work. I have created a separate layer but after using the brush when I release nothing happens. I have reset the tool but that doesn't seem to do anything either. Very frustrated. I thought sample all layers was the default setting for this tool? Thanks
