Yellow triangle on reminders app
I opened my reminders app and it has 2 reminders lists. One is purple and one is blue. The purple one has a yellow triangle with an exclamation mark on it. Does anyone know how to fix it or why it’s here?
Question marked as
These reminders are warning that they will not sync with your other devices because they are not on iOS 13 yet.
Upgraded reminders aren't compatible with earlier versions of iOS and macOS. If you upgrade your reminders on your iPhone with iOS 13 or later, your other devices — like your iPad and Mac — can’t access the reminders until you update your iPad to iPadOS or your Mac to macOS 10.15 Catalina. Learn what to expect until all your devices have the latest software.
You can always see your reminders on a Mac or PC by signing into iCloud.com with a compatible web browser.
