Attribution issue with coversions

[ahmednabik]

I am trying to understand how conversion attribution works with Umami. I am using umami on a simple app https://toastful.io where users generate a speech and on the preview page, they click the payment button to unlock full speech. The payment button takes them to lemonsqueezy page and after the payment is done, they are redirected back to 'view speech' page which counts as a "sale" in my funnel.

However, in my umami, the referrer for this page is lemonsqueezy for all sales instead of the original referrer of the traffic (google, facebook etc.).

Is there a way to correct this misattribution?
