I confirm the issue. One detail that should be noted is that during the first connection DNS works, but it leaks! I.e. if you are using a VPN service for privacy purposes you'd expect NM to pick up the DNS settings from the VPN provider (like openvpn from terminal does) and don't use your home router as a DNS server while the VPN is on.
Subsequent connections don't have any DNS working, not even a leaky one.
