Amazon Cloud Sync not working

I have a 516 and just upgraded to 6.5.1. I was intrigued by the amazon cloud feature. So I'm trying to get it to work. 

I've authorized the connection and it created a new share on my NAS. However, I am unable to get it or any of the other shares to sync. I'm at a loss for what to do. I've tried putting files in both locations in amazon drive directly and on the amazon share and neither of the files show up in the other location. 

The system logs don't show anything uself. and the amazon cloud app logs look like things should be working.

so i'm guessing that things should be syncing. 

I did enable the dropbox one and was able to get it to work fine. However I want to sync multiple shares so dropbox doesn't seem like it will work for me. 

In the amazon cloud app settings at first i had multiple shares selected. I have turned that back down to the amazon created one.

I had snapshots set to never. I have since set it back to hourly. 

I have turned the applicaiton off and on again. 

I have even tried rebooting the nas. 

Not sure what else to try. Anyone have any ideas?
