Back up ToDos in iCloud! I lost all my ToDo record for 5 years when I had to delete and restore the app.
When my app malfunctioned and I had to delete and restore, I was told all my data would be saved. That was because Yunasoft assumed I meant reminder when I said to do. Reminders are saved in iCloud while to dos are not. I have lost 5 years of my life’s activities because of a glitch. I hope this can be fixed.
