It sounds like the discrepancy is likely due to the limitations of Shopify’s “Live view” rather than an actual issue with your TikTok pixel or Shopify analytics.
Live View Lag: Shopify Live view may show inaccurate or delayed data for active carts. It’s not uncommon for Live view to be inconsistent, as it relies on near-real-time tracking, which can be glitchy.
TikTok Pixel & Analytics: If you’ve properly tested your TikTok pixel and ensured correct setup, and Shopify analytics shows no ATC (Add to Cart), it’s more likely that Shopify Live view is giving false positives. Double-check the pixel setup, but if the tests show no errors, the pixel is likely functioning correctly.
To verify, consider using third-party tools or cross-referencing analytics over longer periods rather than relying on real-time data.
