Version 2.0 (11015)
Opened App and saw that it was replacing all Pinned and recently opened (not modified) Notes with “A wonderful new note” blank notes. Update time changes from 15 minutes ago (for example) to at time of writing (2023-05-15 7:36 AM EDT) 11 hours ago. Notes not opened since May 6 seem to be OK. I modified an older note 20 minutes ago as a test and it seems to sort normally .
See Screenshot attached: “Colorfront Team…” Note was manually updated.
