The room field has been changed from "Mandatory" to "Optional" when a guest places a mobile dining order. This is now optional to allow the opportunity for pre-arrival guests who do not have assigned rooms yet to place orders for later.
However based on several support tickets, we are learning that guests that are already checked-in may not include their room number.
If you see “NOT_SET” for a delivery order, this means the guest did not enter their room number.
SEE ATTACHED PDF for original communication to properties. This can be forwarded to properties asking questions about the room field.
