Messages and Reminders not syncing

I have messages set to sync between all my devices (iphone, macbook, mac mini) but if I delete a message on my iphone it still shows up in the message app on the other devices.


With Reminders, I'll mark a reminder as completed on one device but it'll still pop up on the OTHER devices.


What's the fix here?

iPhone 16, iOS 18
