The brand will have to delete access from its Business Center. After deletion, the agency ad account will have access back.
After transferring Leads Access Permission to Brand Business Center, the Brand Business Center admin can customize who has access to the leads. The agency can continue managing Lead Gen campaigns and access reporting. But can't access leads.
If the agency has connected its CRM system with TikTok Lead Gen, its connection will be disabled. Brand Business Center admin can integrate their CRM with agency TikTok Lead Gen campaigns.
Brands will ONLY have access to leads. The rest of the campaign setup and reporting will still be accessible by the agency only.
