Is it possible to work on a layered project in Designer on ipad and then take that into Photo on ipad to finish up on some pixel layers (things that cant be done in pixel persona on AD)? If so, how? Is there a way to just open while in a different Affinity product? Or does one save in a particular format to, say, a cloud service like Dropbox or Google drive or icloud? And then reopen? And if that is the case, what is best format to save? Thank you.
