I just received a response from support that they made a backend change that corrected the problem. As you can see in my above post, the problem went away. I hope it has done so for others.
I would say this is a fairly decent response. Support request sent via email on the third (although the first posting on this thread was on the second), fixed sometime on the fourth, notified early on the sixth. We don't know, though, when they first found out about it. Of course one would like faster response on an app we rely on multiple times a day such as Evernote, but it's impossible to get help on so many apps this actually doesn't look bad. And it's within a just over a 48 hour window which is pretty normal for email support.
