What does catalog change many time per days?

Hello,

When I check on https://ads-serve.brave.com/v3/catalog, the catalog changed many times per day, but campagins seem not changed, why ?

I’m sorry, @hihouhou. But we will not be able to discuss this topic with you. If you feel you are experiencing a bug in your experience (ads not counted properly, payout not accurate, etc.), we will be happy to investigate. But general discussions about specific server-side operations of the Brave Ads Catalog or System are not something we’ll be discussing for security reasons.
