Why don't my iCloud reminders appear on my other devices in spite of fulfilling all the listed requirements?
According to the article about the "Reminders" update, I need to run at least macOS Catalina and iOS 13 to sync my iCloud reminders across all devices. My MacBook Air runs MacOS10.15.7 (Catalina), and all of my iCloud reminders are visible there. However, after recently upgrading my other MacBook Pro to Monterrey, "Reminders" shows only 2 default lists and no obvious way to import my iCloud reminders. Similarly, I keep my iPhone up-to-date and it is running iOS 15.4.1 - again, it has lost all my iCloud reminders. (They were all available on all 3 devices until recently!) I checked that I am signed-in to my (same) iCloud account on all 3 devices, and that I have selected "Reminders" in the list of apps that are connected to iCloud. Yet no dice. Could it be that even Catalina is no longer "good enough"?
