What want you sync? You can't sync services.
I save documents to My Document Cloud and I save documents to My Creative Cloud.
I would like to have a single place to save all My documents to.
Can I save My documents created in Adobe Acrobat Pro DC to My Creative Cloud?
Is there a way to move documents from My Document Cloud to My Creative Cloud?
"Is there a way to move documents from My Document Cloud to My Creative Cloud?"
In a browser you can download and uplaod the documents.
Nobody outside Adobe knows why Adobe have two different cloud services - Creative Cloud and Document Cloud. But they are completely separate, as if they were run by competing companies, and you cannot consolidate or synchronize them, nor make apps that are designed to work with just one, work with the other one instead. We seem stuck with this strange situation.
