Nothing Syncs anymore!
There was a time when if I got a text (SMS) on my iPhone it appeared on both my iPads and on my Mac simultaneously. But some time ago everything but the phone gave up on SMS messages. Why?
Also, there was a time when if I read an email on my Mac it would instantly be marked as Read on my iOS devices. Now not so, the iOS devices only update the Read status when I refresh the Mail app. Why so?
