I uninstalled Evernote - then reinstalled using a download of 10.79 (which I had saved) - then ran the AI search , which worked correctly. Then installed the download for 10.80.3 - and then the AI Search doesn't work on this machine.
The AI Search on my laptop in the windows app is not working - every search produces "No relevant notes were found. Try a different search term ". Although on our Windows 10 laptop, there is no such problem. Both machines are using version 10.80.3. Has anybody else experienced this ?
