We have launched upgrades at the Campaign and Creative levels in Portal 3.0:
Channel-Level Status Management: Users are now able to change the channel's status individually. If they want to do a creative refresh in a specific channel or adjust something channel specific, users don’t have to pause the entire campaign. However, they can still manage the overall status of the campaign as usual.
Creative Refresh for New Languages: Users are now able to add creatives to campaigns in any language after the campaign has launched. They no longer need to have all creatives ready in all languages before launching the campaign.
