I think so too!

while running:
$ resolvectl dns
Global: [IP addresses associated with my VPN site] {*}
Link 2 (enp57s0u2u1u1): [IP addresses associated with my ISP] 192.168.1.1 {**}
Link 22 (cscotun0):
$ resolvectl domain
Global: [VPN connection domainname] [ISP]
Link 2 (enp57s0u2u1u1): [ISP]
Link 22 (cscotun0):
where [VPN connection] stands for the address that is associated with VPN.
After stopping VPN:
$ resolvectl dns
Global: [Same as {*}]
Link 2 (enp57s0u2u1u1): [Same as {**}]
$ resolvectl domain
Global: [VPN connection domainname] [ISP]
Link 2 (enp57s0u2u1u1): [ISP]
After $ sudo systemctl restart systemd-resolved.service
$ resolvectl dns
Global:
Link 2 (enp57s0u2u1u1): [Same as {**}]
$ resolvectl domain
Global:
Link 2 (enp57s0u2u1u1): [ISP]
Seems to me there is something "sticky" about the VPN connection?
Many thanks for your suggestions and help!
Best wishes,
Ranjan
