Hello . Recently , when drawing , I have some problems . When I use the " magic wand " tool , and coloring in the space , there are these white spaces left in the corners , and I did not seem to like that . There are more problems like the lines which I draw just sort of , vanish , and I can't redo it back , similarly , there are tones of other glitches which bother me a lot . I can't even add a high - quality image . I would like it to be fixed . This app is only my last hope for drawing .
