i'm having the same problem i use to be able to send my drawings as a pdf in adobe ideas, but since i upgrade to iOS 9, ideas dose not work anymore i found out later it is on longer supported, well fine so i upgrade to to adobe illustrator draw, and only to find out you don't have that option to send a pdf.
Now my problem is i have a home computer with its very own adobe account link up to my iPad so if i send my drawing to illustrator it sends it to my home illustrator, while i'm at work with work having its own account. how can i send my adobe illustrator draw files to my work account if my iPad is link to my home account do i drive back home (2 hour trip) log on to my home computer save it to as a pdf or vector send it to my work then drive back to work and open it (now thats plan silly) i do not want to log on my home account to my works computer due to works rule of having outside accounts everything at work is approved only for work stuff ya da ya da. why did adobe disable the send as a pdf by mail in adobe illustrator draw. again i have 2 accounts one for work and one for home why is it not easy to just share file from one account of adobe cloud to other with out making the vector file turn into a jpeg.
