Problem with Beta 5.0:
I have noticed that since installing the Beta, my devices only get the PiHole's IPv4 DNS address but not its IPv6 DNS address. These values would be shown autofilled in my devices when using PiHole 4 (my service provider uses IPv6 and all my devices are correctly getting IPv6 addresses including the PiHole). The PiHole acts as my DHCP server. Everything still works, but I was curious as to why this was the case.
