I plan to use the ADM to message from a web server a simple message to trigger certain events on several Amazon devices.
This is all working with the new API when I send the correct Registration ID (Captured from debug and sent with the message).
But the Registration ID is different for each device, is it possible to send a wild card registration ID to send to all devices within my group (much like Firebase does if you subscribe to a topic) ???
