Spectator Messaging no "Send Message"

I've tried everything with Live Track and Live Event sharing.  3 different phones, iPhone and Androd.  The map and my tracking works.  But on all phones there is no option for the receipient to send me a message.  The "Send Message" button doesn't show up at all.  Anyone figured out how to resolve this.  I've had a ticket open for a week and have just received useless help, just more basic questions.  I started my LTE subscription, but being able to send messages was one of the primary reasons for turning it on.
