There appears to be an issue where Mobile Creations are not available via the Illustrator or Photoshop desktop apps, like seen here.
Additionally, Mobile Creations are not available via Creative Cloud file syncing. The only way to view these files are via the View on Web function.
How do I enable Mobile Creations in the desktop apps?
That tab was only in Illustrator CC. And, unfortunately it is no longer there.
I'm not certain why the decision was made to remove it, but from what I understand there is not a plan to bring it back. The only way to get Draw/Sketch art to the desktop is to use the Send to Illustrator/Photoshop CC function in the apps.
That would effectively kill the apps for me. I need to be able to access all of my mobile creations from my work desktop or I won't even bother to use the apps. It is quite frequent that I need to work on something I began on my ipad and finish it later on my desktop. Please bring it back?
