hi, I very recently got the ink & slide and iPad mini 4 (because ink didn't connect to my 3rd generation iPad) and although the ink seems to work fine, the slide doesn't work at all. I have tried turning the enable slide button on the line and illustrator apps off and on but still doesn't seem to work! I really want to start using it, and I know the features can be used without the slide but I want to use the slide that I have purchased! Am I doing something wrong!?
