Reminders not syncing since iOs 9.3
I use reminders a lot and have never had any problems with notifications until iOS 9.3.
Now when I change or acknowledge a reminder on any of my devices (iPhone 6s, Apple Watch, iPad etc). The button highlights and in some cases the reminder disappears but give it 10 minutes and it's back to it's original state.
They only seem to change or disappear when my Macbook Air is open.
What is causing this and how can I fix it?
iPhone 6s, iOS 9.1
