Has anyone tested restoring a cold card multisig from seed phrases?

Or even better - create the multisig with cold cards then restore with a different device?

Reason I asked is it appears coldcard does not follow BIP178 spec, and have their own custom fields (global_xpub) - so I wonder how this would work in disaster recovery?? 😅

I assume you mean bip174? When I've run into incompatibilities on global keys it has been due to the device or software receiving a psbt version it is incompatible with. Last I checked, coldcard only supports v0. Maybe check if the one which won't work is a v2?
