SpaceX Starlink dhcp6 issues

[Deekers]

I want to lead out with, I am 99% sure this has to do with Starlink "testing" ipv6 prior to its coming out of beta. I disconnected the SpaceX router (which blows compared to even a decent ASUS router) and hooked up my own RT-AC3100 running 386.2_2.

Everything works perfectly with the exception of ipv6, which works sporadically....but is nearly transparent to me since I just leave it in "Native" and move on with my life. In the logs, I've noticed this happening roughly once a minute. My only questions are:

What would cause this?
Is it some setting I've messed up?
Should I be concerned?

I get this once an hour, which is when my ISP renews its leases (IIRC this is a result of changes between 384.xx and 386.xx code bases). At a guess I would say that if the IPv6 connection is flaky, then it maybe be constantly renewing and hence the messages,

For those who one day find this on google......

I managed to get ipv6 working consistently on my merlin router and posted the how-to on reddit:
