One week ago I upgraded my Unifi from 500Mbps to 800Mbps, and was given a new router - Skyworth GN630V.

Everything looks good except one thing - the IPv6 which I suspect might be a firmware bug. Apparently, the IPv6 Delegate Prefix became invalid after 24 hours and the only way is to reboot the router. The assigned WAN IPv6 is still available, however the assigned Delegate Prefix (which is used on the LAN side) no longer works.

In the WAN status screen, the IPv6 Delegate Prefix displays a dash after 24 hours.

Anyone here also faces the same issue?
