When first launching Reminders after the iOS13 update, it asked if I would like to update the Reminders database. I picked yes to see the new features but now my iPad(not on iOS13) does not sync properly. Has anyone found a way to downgrade the database? If I reverted to iOS12 and then upgraded again, would it start syncing with iOS12 again? I tried uninstalling and re-installing the Reminders app on iOS13 but that didn't fix it.
