So I have some drawings I did in Express on my iPad that I’d like to transfer for use in Pro.  Both programs are on my iPad.
I could do the whole pdf/jpeg thing but I want to be able to maintain the layers and continue drawing.

I’d also like to see a solution to this for Ipad
Thanks in advance

iOS applications are sandboxed, meaning that they can’t share their contents directly.
The only way is to use a central location where any app can write/read.
For example, the Photo Library but then you lose the layers.
For now there is no other way of doing it.

its a shame the express version doesn’t allow you to share with dropbox because that would solve this problem
i.e. save to dropbox a as psd from express gallery, download to pro gallery from dropbox as a psd

Agreed. Easy fix Autodesk? Hmm? Hmm?

Same problem here, on Android.
