We highly recommend you update your tracking parameters to get the most out of our platform. The benefit of updating the parameters will be greater than the cost of the learning phase.
Meta
The learning to processing phase should only take a few hours. We suggest you start with changing a subset of the ads and observe how it affects the campaign/ad set/ads, and you can update tracking in batches to better manage this process.
By updating the UTM tracking, you will need to change the URL. By changing your URL this will trigger ad review.
TikTok
When you update the URL it resubmits the ad for review and restarts the learning phase. Ad review usually takes 2-3 hours (but can last up to 24 hours).
