Peter, good afternoon!
Going through our service / activating the extension in the browser before making a purchase is the main condition for calculating a commission by the store. If it is not recorded, we do not receive information from partners. You can always view your transitions in the "Orders and Finance" section.
Since you did not go to the store on November 19, the cashback cannot be credited. We recommend that you reinstall our extension or go to the "Go to the store" button. If you have any questions, you can always contact our care service (section "Help").
Yours faithfully,
LetyShops team
