I too, am having the same problem. My native Samsung message app no longer works using the "Chat" feature. I know it's the app because other messagin apps like "WhatsApp" work perfectly. I like the Chat feature on the Samsung app because it lets you know when the message was delivered and then read. It also lets you know when the other person is writing you back by showing the infamous 3 dots blinking in sequence. The message is in blue letting you know you are in "chat" mode. However, this all stopped as of yesterday. WHY??
