Until now, advancing a campaign to Proposal status (or beyond) required at least one brand contact to have activated their account. During rollout phases, when brand contacts haven't yet been responsive, this prerequisite could stall your campaign progress.
This constraint is now lifted: as long as a contact exists for the brand, you can move the campaign status forward, even if that contact hasn't activated their account yet. Only cases where no contact at all is associated with the brand remain blocked.
