Hi there @Seller_t4LNYxpCy8kdQ,

For your Prime trial performance metrics, here's what to check:

• Have your parcels received their first Royal Mail carrier scan? (Amazon starts tracking from this point, not from dispatch confirmation)
• Have you confirmed the shipments in Seller Central immediately after dispatch? Late confirmations can affect your metrics.
• Verify these are Prime-eligible orders in your trial.

If everything looks good but you're still not seeing any data, reach out to Seller Support with your specific order numbers and they can investigate further.

For more details, check out our help page on Seller Fulfilled Prime performance metrics.

Thanks! Ezra
