Have you made sure that /etc/resolv.conf is symlinked to systemd-resolved's config? Usually ls -l /etc/resolv.conf should output something like this: /etc/resolv.conf -> ../run/systemd/resolve/stub-resolv.conf. If that's not the case, systemd-resolved may not be detected.

The symlink does exist, but in my system it is, by default, symlinked to ../run/resolvconf/resolv.conf, instead of ../run/systemd/resolve/stub-resolv.conf.
