I bought Sketchbook Pro to do cartooning. I drew a doodle and then tried to export it to my iMac to work on it further. It wasn't easy finding out how to export it, I had to search the web for a PDF of the manual. Then the manual told me to press an icon that looks like a flower with an arrow coming out of it. On my iPad, that icon is always dark and doesn't respond. Does anyone know why?
