USG LITE 60AX and IPv6 support

Lohkamp

I have an AVM FRITZ!Box 6890 LTE that worked marvellous with both IPv4 + IPv6 on a German Telekom VDSL incl. port forwarding and am quite shocked that our new USG LITE 60AX does not seem to support IPv6 to the internet or even DNS forwarding.
nslookup anysite.xy
is not answered but ping is working, however only with IPv4.
Was is a real big step back to replace the FRITZ!Box as a router by the USG LITE 60AX?
The FRITZ!Box is without any configuration change (except the IPv4 subnet) connected to the WAN port of the 60AX.
