Trying to share reminders across all devices but ipad2 does not get them? Mac, iPhone 12’s and newer iPad share them

Just to confirm, iCloud for Messages does not work on an old, 10-year old, 2011 iPad 2 running iOS 9.

iCloud message and update for Messages was never available to older iPads running iOS 9 or 10.

Maybe for iOS 11 and 12 devices, but NEVER available to iOS 9 or 10 devices.

I tried long time ago to set this up both my wife and I who still own and use 9 and 10-year old iPad 2 and 3 models AND much newre iPad models, with no success ever on these old iPads.

Sorry.

When opening your reminders App for the first time on iOS/iPadOS13+, you were presented with an option to “upgrade” the Reminders App. You will also have been presented with a warning that compatibility with devices running earlier versions of iOS would be lost.

If you clicked-though and accepted the upgrade, you triggered a one-way update for your account on Apple’s servers. Once triggered, you cannot return - and Reminders for iOS12 and older versions are forever incompatible with newer devices.

Sorry, but for iOS12 and earlier, the Reminders App cannot now sync’ with newer devices.

Upgrading the Reminders app in iOS 13 or later - Apple Support

The iPad 2, released by Apple in 2011, cannot update iOS beyond 9.3.5. That iOS version was released five years ago.

I’m fairly sure Reminders has been substantially upgraded since way back then.

You’re welcome. Enjoy your Apple gear.
