I thought I had sorted it by turning automatic connect on in it's settings but it seems to still happen now, perhaps due to rebooting or coincidence. Not a big issue to quickly click and I have morr important things to do but I should probably look into it a bit more.

Hi,
from connman manpage:

 -r, --nodnsproxy
              Do not act as a DNS proxy or support  external  DNS  resolving.  Depending  on  how
              ConnMan is compiled, it will by default direct all DNS traffic to itself by setting
              nameserver to 127.0.0.1 in resolv.conf(5)  file  or  leave  DNS  management  to  an
              external entity, such as systemd-resolved. If this is not desired and you want that
              all programs call directly some DNS server,  then  you  can  use  the  --nodnsproxy
              option.  If  this option is used, then ConnMan is not able to cache the DNS queries
              because the DNS traffic is not going through ConnMan and that can cause some  extra
              network traffic.


So add -r to the options of the script from where connman is started.

look also at manpage connman-service.config (and manpage connman.conf not so interesting)
