Can't search for anything since this morning - I keep getting "No notes found" message. Tried signing out and signing back in, closing the app, force reloading. But nothing works. I am on macOS Catalina 10.15.7. The search was working fine on this same OS till yesterday, and not sure what happened today. This seriously hinders my work. Hope the Evernote team can release a fix soon. Update: Just checked, and confirmed that besides the app, the search also does not work in Evernote's web-interface opened in browser.
