I have the same issue. It's also bad on iPad.
If I share from some other app to Evernote, then when I next open Evernote, it says 'Clipping <whatever>'. Sometimes is does this more than once, so I end up with duplicates. If I don't open Evernote for several days, or a week or more, I might have a number of notes which haven't been clipped yet. I assume that if a webpage I am clipping changes in the meantime, the clip might not contain the content I want.
I am really frustrated with Evernote. They really need to concentrate on having rock solid core functionality and nail that before adding new features. I have been using Evernote since 2008 and feel there has been a major regression in the last year or two.
