Apple Pencil Stopped Working

I've been using Fresco for the past two months on my iPad with my Apple Pencil, but starting last week it doesn't really work anymore. I've look at other discussions with people having the same problem, and I have tried out everything people have suggested, but it doesn't seem to work. So I was wondering if someone could help with this problem. And yes, I did try to adjust the stylus pressure and it doesn't work, and I've also deleted and reinstalled the app. So if someone could please help, that would be great!
