Can you please email me output from "tcpdump -n -vvv -i <wan> port 546 or 
port 547 or icmp6" as your WAN is trying to get DHCPv6-PD ? Or if you dump 
that to a pcap and email it to me (or make it available somewhere for me 
to download).

I have 18.06.1 working with homenet on WRT1200AC,dual uplinks (two 
different vlans on WAN), getting dual stack from both ISPs, /56 from both, 
and both are announced out on LAN. I even configured bidirectional SQM 
with CAKE on each uplink (250/50 and 250/100 respectively) and it seems to 
do the right thing.
