Conversion Events: In some cases, the data might not show up until there's at least one conversion per group in your experiment.

trackingCallback

is implemented correctly and firing. - Check your assignment queries and test them directly in your data source. - Ensure your analytics integration is set up properly. - Wait for sufficient time to allow for data sync and potential conversions. If you've checked all these aspects and are still encountering issues, you may need to investigate further or reach out to GrowthBook support for assistance.
