IPv4 only no IPv6 network connection

IPv4 only no IPv6 network connection
Just switched to Verizon 5g Home Internet today and noticed my xbox one's NAT type had changed from open to moderate, which talking with Verizon we got switched back but also noticed that its only running the IPv4 and not including the IPv6. I go into my
admin on the router which I can see the IPv6 address but no way to enable it on my xbox. Also now getting much lower download speeds (~20-40mbps) and increasingly high latency (~60-130). Yet I will run test speeds with my computer and will get higher down
speeds(~200-350mbps) and my ping will settle around in the 30s.

my iPhone will also only show low download speeds through out the house.
