mail not syncing between ipad and iphone or macbook
Two days ago anything I have done in iPad mail app has stopped syncing across to either iPhone or MacBook. For example, emails sent from ipad don’t update to other devices. Same with any emails read, deleted or moved. I haven’t changed any setting. I have re-booted all devices, closed and re-opened mail app, all to no avail. I have been unable to find a solution that works. All devices are updated. Can anyone assist please?
iPad, iOS 10
