help understanding DCO mode and routing

[SpaceBass]

hey folks
I'm struggling to get a s-2-s converted to DCO mode and I think it may be a misunderstanding of the documentation.

Our site to site tunnel incudes multiple local networks and multiple remote networks.

Is that why the daemon fails to come up with DCO enabled? Would we have to create tunnels for each remote and local network routing combination?

Simply flipping the DCO flag off allows the tunnel to work.
