I´m doing some standard verifications in a freshly deployed 365 Commerce demo environment, Tier-1. Just to make sure all the parts are working properly and have the connections to the front end Contoso online store.
Distributsion schedules, sessions etc work fine, but not the catalog publish for some reason. This error message is new to me in the catalog publish validations.
Full message: "The channel Contoso online store has not been published. Product listings can't be created."
