Hello! Yesterday, I finished drawing a comic. I was supposed to color it in, but the color fill was not working on anything on the drawing. I tested using the fill color on a separate drawing and it worked. It’s only this one drawing that can’t be colored using fill at all.

I do the press and hold technique to color. My iPad Pro is version 12.3.1 and is up to date.

Update: It’s gotten a little better. I can only color small objects but that’s it.
