A while ago there has been an EN update that changed the way notes are duplicated.
I can't say what release it was, because it is impossible to search with Strg-F on the evernote release note site, because there the bad habit was used to let all release notes disappear in collapsible and expandable areas.
The title says it: If you duplicate a note, you don't end in the new duplicated note, but in the all notes view.
Can you change it to the former habit: Duplicate a note and ending in that duplicated note.
