My OS is windows 10 and I have the latest version of Affinity Photo.
As the title says, whenever I use any other brush that does not require wet edges after using a brush that does, that option does not untick and I have to manually change it.
So. Click on a water color brush(wet edges is automatically selected). And then click on any standard brush (wet edges is still selected).
Not a hassle to do, just figured that this wasn't intended.
That being said, that was the only water color option change that was obvious to me, not sure if there were other options that automatically change.
