Just as the title says, searching tags does not work at all in the both classic and beta editor. I have over 800 notes, which are all tagged. Even when I open a note, and click the note's tag on the bottom and select "Filter by Tag", I still get the "No notes found. Try using a different keyword or filter" error. I didn't have this problem last week on Thursday.
Furthermore, multi-tag search never works for me. I know that is a different issue, but now that tags don't work at all makes it really difficult finding the material I need.
I am using Evernote on Windows 10 on both Chrome and Opera. My computer and browsers are up to date.
