My wife and I are on sprint. We have our own accounts. My wife has an s9 and i have an s9+. Originally, my wife and i could get recieved notifications and the correct color text was happening for enhanced messaging. Then, all of a sudden, we stopped getting the receipts and the color went to green for quite a while. We chalked it up to an issue with android and that it would eventually iron itself out. Then, we got the blueish colored texts again,but they were still lacking the receipts. She can text her friend and get the receipt, and I can text my son and get them, but we cant get them from each other. What is going on here? I would say our settings were off but we are getting the receipts from others. By the way, we are both on the latest update.
