BkkGreg is very right. I am trying to use Affinity Photo for two years plus did a thorough online course, but Affinity Photo is letting me down time and time again. One of the hundreds of little problemes I have is the following. I use the freehand selection tool on a rasterised layer. Deleting the selection doesn't work, nothing happend when I press delete. After ten minutes of trying to solve this problem I use the Rectangular Marquee tool and press delete. The selection is deleted. How is this possible?
And how is it possible that Affinity still doesn't have the selection-option "select similar"?
I am afraid I have to go back to the, in my opinion, totally corrupted Adobe company to return to Photoshop.
