🚨 After upgrading your reminders on iOS 13 that are synced to iCloud they will stop showing up on other devices
According to an official statement by Apple:
“Upgraded reminders aren’t compatible with earlier versions of iOS and macOS. If you upgrade your reminders on your iPhone with iOS 13, your iPad and Mac using the same iCloud account can’t access your reminders until iPadOS and macOS 10.15 Catalina are available. Learn what to expect until all your devices have the latest software.”

Here is something important to note:
If you use multiple devices and some of them are not eligible for the updates, then you won’t be able to access those specific reminders. e.g. iPhone 5S, iPhone 6, iPhone 6 Plus, iPad Air, iPad mini 2 & 3. (and all devices that came before)
