Since more than a month and through several updates, the sorting of the notes haven't worked in the Windows 10 program for me. The sort by latest edit works from the start screen, but not when I choose all notes or a tag. I see no discernable pattern of sorting to the list of notes that come up, other than that they are usually pretty old. Sometimes when I choose to show notes by tag, I don't even get the right notes, but notes with a different tag.
This problem only occurrs on the Windows 10 client, not in the web browser or Android app, but I get the exact same problem using the Windows 10 client on different computers.
