You will need to submit a Missing Cashback request for every order that's missing.

Here's where you can do it:

1) On the mobile app, click on the user icon and search for "Report Missing Cashback".
2) On the website, click on "Cashback Overview" and you will see a red button for "Report Missing Cashback".

Alternatively, you can view the step by step to submit a Missing Cashback request here.

IMPORTANT: Missing Cashback submissions must be within 30 days from the purchase date. Any submissions past the specified time are invalid and will not be investigated by the merchant.
