Hi, I am having the same problem. Has there been an outcome?
Problem: I have added the Evernote Add-on to my Gmail ( access my Gmail via Chrome on my Mac book) and when I save the email to Evernote it does not include the attachment. The other functions work eg saves to the notebook I choose and includes the tags I add. Please note: This is for Evernote for Mac users and I have been a long term user of Evernote so I am pretty good at troubleshooting and can't work this one out! I have been forwarding emails for years to my Evernote email address and this has always included the attachments.
I would really appreciate your assistance, anyone
