I test it with v0.2 also not working for ipv4 and ipv6 because it ignores the

annotations: metallb.universe.tf/allow-shared-ip: piholev6

Failed to create endpoint for service default/piholev6tcp: endpoints "piholev6tcp" already exists Failed to allocate IP for "default/piholev6tcp": can't change sharing key for "default/piholev6tcp", address also in use by default/piholev6udp
