Netgear Router Nighthawk not supported with Spectrum Internet

I recently bought a Netgear Nighthawk router from amazon (AC1900 - Model C7000v2/C7000-100NAS).
Set it up and called Spectrum to activate my internet. I received a warning everytime I try go to a site saying something along the lines of: "This modem is not on compatible." 
Called Spectrum again and asked about the situation. They said they block all other compatible modems that are not on the approved list (Link above). 

I keep reading online that it is a working router with Spectrum. Does anyone have any news on the change of approve list?

- Thanks
