I'm also having the problem. 1) Capture photos of cards directly in the Evernote for Android application. 2) Notes sync properly to both the web and Mac desktop client (6.0.8). I can see both the photo of the card and the text. 3) No changes can be made to the captured cards through the Mac desktop app or the Evernote website. Even if you hit "save" manually via the Mac desktop app there are no changes allowed. 4) I can make changes and edits in the Android app and those changes are synchronized to the web and Mac app.
