I am currently using with an ISP that provides an IPv6 /48 prefix delegation. While the router connects successfully to the ISP and obtains IPv6 connectivity, it appears to only request and assign a single /64 prefix on the LAN side.

As a result, my LAN devices are not receiving global IPv6 addresses, since the router does not seem to advertise or distribute subnets from the full /48 allocation. I have also been unable to find any option in the firmware to adjust the prefix delegation (PD) size or to manually configure subnetting.

I would like to request that TP-Link add support for configurable IPv6 Prefix Delegation sizes (for example, /48, /56, /60, /64) in a future firmware update. This feature is essential for users whose ISPs provide larger IPv6 delegations, and it would ensure the router can correctly distribute IPv6 addresses across LAN devices.
