Please see this image for ref. I am not sure if this helps. All I want to display broadcast message on Waiter tablet that FOOD IS READY when the chef tablet " Kitchen order ready" is clicked.
Don’t understand.
Your not showing your broadcast message action.
Would want to see the broadcast action and the message received rule. But like I said that you seem to have missed is I’m pretty sure message received a thon won’t fire while a ticket is open on the receiving device.
