how can I use adobe dc to synch with my endnote pdf articles after i annotat them

I use endnotes a lot to find articles for my research.  In the same program I use it to find full off articles.  I recently purchased a kindle and now I would love the option to read and annotate on my mobile device (kindle fire) then synch back to the original documents on my laptop. So utilizing the adobe dc application I put a few test documents annotate them. I then Let them synch to the cloud but when I examine the original document on my laptop it remains unchanged.  The same is true for the document if I edit in my laptop I dont see the document changed in the cloud.  Am I missing some somethin?  Is adobe dc making a cloud copy that I would have to override the original document?  Please let me know.
