Amazon.com sync is not working

Question

Amazon.com sync has not been working for more than a week, now. New orders show up, but the status never updates. The view on web option works.

Amazon synchronization is one of the best features of this app. Please fix it!

I'm not sure this is a duplicate. That thread appears to be about the beta 6.0 version. I'm having the problem on the 5.8.1 version.
