Meraki MX85 DHCPv6-PD issues

[incinrea]

I'm running MX85 with 18.205

I've issues with DHCPv6-PD

After some time, the dashboard says that my VLAN Assignment IPv6 Subnet Prefixes status is "Expiring Soon," causing my endpoint not to get IPv6 while at the Delegated Prefixes status; the Prefix should expire in another 3 days.

Please advise.

I need to reboot my MX85 multiple time to get back the DHCPv6-PD. Here is the result after reboot for the 5x time (i'm not kidding)
