Once I auto-upgraded to 10.59.5 on Windows 10. As far as I can tell, Tag-based search has some serious bug, is basically broken. The "Filter-by-tag" option on a note tag no longer works, and selecting a tag in the Search box also seems broken / non-responsive. This is a very basic bug. I've used Evernote on Windows for 10 years and made no other recent changes to my system. I'm very confident this is a bug. Thanks. Fraser
