After binding DJI Avata 360 to the combo's remote controller, why does a "Connected device not bound to aircraft" prompt show when I connect a different remote controller or goggles?

The DJI Avata 360 must be bound one-to-one with the remote controller or goggles in use. To switch to a different remote controller or goggles, you must rebind; otherwise, you can fly up to 20 times with the new device.
