Hi, @Vero I'm having similar problems since upgrading to Alfred 3. I used to be able to use the workflow, but now, after initializing the hot keys (for example, "ent") I see the option to search my Evernote Titles, but when I hit Tab or Enter (which used to take me to the next stage, entering a title of a note), it just defaults me to Google Search in Alfred. Here's an example of my attempt to search to-dos.
One thing to note... On one of my Macs, the Evernote workflow works perfectly. But on a different Mac, it performs as described above.
