I'm also having this issue. Shortcuts I add to Evernote for Windows do not show up anywhere else. Adding shortcuts works fine between iOS and Web and Mac. If I change my shortcuts on any of those devices, they will sync and also replace my Windows shortcuts with that shortcut list. It seems like the Windows client is not uploading any shortcut changes but still downloading shortcut changes. I've tried clean re-installing Evernote, disabling HTTP Batch Request, made sure "Sync Shortcuts" is enabled in Evernote... Not sure what the solution is.
