This is my professional "work" MacBook Pro (13-inch, 2017).
All of my Stickies are gone after launching the app on a Monday, one week after upgrading to macOS Catalina. I uses Stickies for code snippets and reminders. After this fiasco, I will certainly not be using Stickies for anything, ever again.
The Stickies database file "last modified" date is one week before the upgrade. Odd, since I've used and updated Stickies since that date.
Any help in restoring them? I do not use Time Machine.
