8900AX-1600 R2, BT Infinity & IPv6

Ok, so I'm a bit stumped. I'm on BT Superfast Fibre Unlimited 1 and originally had a HG612 modem connected to an Asus RT-AC66U (running Merlin firmware) and IPv6 worked fine:

Got my hands on a 8900AX-1600 R2 as I wanted to go to a one-box solution. Suddenly, IPv6 is a no-go:

However, if I connect the 8900AX-1600 to the HG612 modem, I get this:

The 8900 is running the latest 2.50a.d23 firmware and has been completely factory reset and reconfigured from scratch multiple times. In a nutshell, my one-box solution doesn't work with IPv6.
Anyone got any ideas?

Never thought to test it until I saw your post, but I get the same on the latest firmware (see attached).

Ok, more weirdness. (This next bit was done using the built in VDSL modem)
When the router is restarted, I actually get IPv6 connectivity (as tested with ipv6-test.com) for about 5 minutes, at which point it stops working again. At no however time does the router show as having received an IPv6 address on the WAN interface.

Problem solved.
Decided to go back to the Asus setup while this was being investigated and noticed that it too had begun the same 5 minute drop out issue.
After lots of head scratching and investigating, I found the answer; I run a Windows Server 2016 machine on my network which runs my DNS and DHCP. Somehow this had some static IPv6 addresses in the DNS records for the server itself and a couple of other devices on the network.
Deleted those DNS records and - hey presto - all sprang back into life.
