Why this happens
Soco’s higher-commission links only apply to new TikTok Shop videos or new TikTok Shop Live sessions you create after adding the higher-paying link to your showcase.
Videos and Lives published before you updated the link will always track under the commission rate that was active at the time they were posted. This includes viral videos that are still generating sales.
When the higher commission rate applies
You will receive the higher rate only on content created after the correct higher-commission link is already in your showcase.
Summary
Older videos keep their original commission rate.
New videos and new conversions will track at the new rate once the higher-commission link is in place.
