NBR 750 IPv6 please!!!!

I've been recommending the older LBR20 and the new NBR750 for clients who need a router for an LTE/5G connection in lieu of cable in the area. I've even been using an NBR 750 at home for a tester for about a year. I love the router but HATE how Netgear has hobbled ipv6 support for the wireless (LTE/5G) connection. It's baffling to me that the router supports WAN IPv6 connections if connected to an ethernet WAN link (cable/DSL/etc), but does not support it over the wireless connection, despite the router being capable of receiving an IPv6 address over the wireless connection. Why not allow the router to provide IPv6 addresses even if they are strictly link-local? Or better yet, why not allow the router to provide IPv6 addresses from the prefix delegated to it over the 5G/LTE connection? 

If you go into the Advanced/Advanced/Ethernet IPv6 in the configuration section for an NBR750 you get an error if you make any changes "FAILURE: No Ethernet Cable is plugged into the Router Internet Port."

Can you please fix the firmware to enable IPv6 for users who are using this strictly as a LTE/5G router? Why hobble this? I've had to stop recommending these for clients and frankly have stopped all Netgear recommendations as the seeming arbitrariness of this (especially considering the importance of IPv6 support for things like gaming when having to deal with CGNAT) leads me to question just what Netgear is trying to do.

Please fix this!
