Why does my message show a read receipt on one device and not the other?
I use my iMessage on both my iPhone 5 and my Macbook Air, however, occasionally when I send a message from either device it shows a read receipt from the other person on my mac, but not on my iPhone. The message on my iPhone stays as 'delivered' until much later and then appears to be read (I still eventually get read receipts on my phone), but my mac will deliver the message and it appears that the message has been read later on, but shows the read receipt way before my iPhone does. I don't know if this is just a glitch and they haven't actually read the message, or if my mac book is somehow showing the read receipts first??
iPhone 5, iOS 9.3.2
