GL-MT300N-V2 not receiving IPv6 from phone hotspot

I have already looked at GL.iNet GL-MT300N-V2 & IPv6/DS-Lite. Tried it, I think it turned ipv6 “on”. But I think my problem now is that the IPv6 isn’t going from my phone to the router. If I tether my phone straight to my PC however, is showing that it is supported on both. But through the router, only IPv4.

IPV6 support on MT300N-V2 will be available in firmware 3.200. It will be available online in January
