Samsung Galaxy Tab S7 - Just downloaded Message+ - install went fine
I can send a message from tablet and see what I've sent on my phone. The recipient is typing message shows. I don't receive the response. I do see it all happen on my phone and in the online app.
disconnected and reconnected
I've had this issue too. In fact, it has happened on and off for YEARS. I'm not the only one, as you can see by searching through this forum. Verizon clearly has no interest in fixing this.
