Thanks, Leigh. I’m afraid I don’t have a layered file to share since I found a work around and fixed up my files. This is a closeup of one piece that shows the lines around layers that appear when saving file. I think the outline is appearing around imported png images. The workaround I do now, is to vector crop and then rasterize and trim each imported png. Hope this helps. All of the pngs I imported were saved from Procreate.
As for the paintbrush not working, I have no idea why that was the case for almost a week, but, thankfully it is now working!
