Something quite strange is happening on my notebook: Whenever I do snap install or snap remove, systemd-resolved forgets all DNS servers for my wifi interface (as per resolvectl). The network is managed by NetworkManager in a standard Ubuntu/Gnome session.
$ snap version
snap 2.56.2+22.04ubuntu1
snapd 2.56.2+22.04ubuntu1
series 16
ubuntu 22.04
kernel 5.15.0-46-generic
Like so:
