If you have installed a brand new pixel, or have recently installed a developer-mode pixel (a few months of use), we strongly suggest that you:
Remove your previously installed developer-mode pixel (if any). Make sure it is not currently used by any active campaigns.
Return to the channel set-up and click Create New to create and install a new pixel. Ensure that the Advanced Matching feature is ON to improve the match rate between TikTok ad clicks and conversions that happen on your website.
If you are an established developer-mode pixel user ( >than two months of use with a track record of success without issues), then we recommend:
Proceed with the channel set-up and click Create New to create and install a new pixel (you will be able to deactivate it later).
Keep using your existing dev-mode pixel.
