Getting stuck on connecting a ROS 7.15.3 router to a Juniper via OSPFv3. We have OSPFv2 working fine and lots of OSPFv3 connections between Mikrotik routers, but when trying Mikrotik to Juniper, it is failing at INIT state. A packet capture is just showing hello packets to and from the two routers via link local addresses.
Mikrotik OSPF (some v2 left in):

We can ping across the interfaces on IPv6 just fine to the transit IP addresses on each side. I don’t think we really need the loopback IPv6 address but it’s there to remain consistent with our OSPFv2 settings.
No firewall is active for IPv6 at the moment.
