Verizon On Demand Issue

I just purchased a EX7000 Nighthawk AC1900 and everything works great except, my verizon fios "on demand" stopped working.  I've spent about 5 hours talking to verizon and reseting STB units, but like I keep telling them.  There must be some setting on either the extender or the gateway router that is causing the problem.  The gateway is a verizon MI424WR.
