First, I want to thank you both for your help. I couldn't see the scan on my phone or via the web. But when you brought up the sync issue it occurred to me that I may not be logged in properly to scannable b/c previously I had changed my Evernote password but never updated it on scannable. That was the problem. My fault--sorry. Thanks again for your help!
On iOS 6S the Scannable app is not sending a scanned doc to Evernote. I get a message saying "Scannable Document saved to 'Scannable' notebook in Evernote." I had to manually create a "Scannable" notebook, but I still cannot find the saved document anywhere in Evernote. In the Scannable app setting my default notebook is "Scannable" and I have a "Scannable" tag that is supposed to be added. Yet still no note or tag anywhere to be found. What am I doing wrong? Thanks.
