I just traded in an iPad mini 4 with the latest iPad Pro 11 inch with the Folio keyboard plus Apple Pencil. Works very well with Shapr3D. Great program!
After using the Pencil for about one week with the iPad Pro I noticed a little problem with the pencil not doing the right thing.
A closer examination of the pencil I noticed the tip was a bit loose. After tightening the tip again everything went back to normal.
Just a little experience to save the day!
