I do not understand how I can refine a mask a second time (in Affinity Photo). To make more clear what I mean, this is what I have done and where I run into problems:
I made a selection; used it to make a Mask layer; right-clicked on the mask layer and chose Refine mask; made some refinements and chose Apply. So far all good, but now I want to make more refinements, but if I choose Refine mask again, the refinements I made previously seem to be lost. If I press cancel in the Refine Selection panel, then I see the previous refinements are NOT lost, but I cannot figure out how I can apply more refinements, working from the mask that already was partly refined.
This is driving me crazy, so any help would be greatly appreciated!
