In addition to browser settings and browser extensions such as Adblock (details for: Firefox, Chrome, Safari, Safari for mobile devices/tablets), other factors may prevent cashback from being activated.
Pay attention to these potential problems:
Computer antivirus program:
Some antivirus programs provide protection against online ad tracking. If you encounter issues, consider disabling the antivirus before activating the cashback and during the entire purchase process.
Internet provider:
Some less well-known Internet service providers can cause problems with activating cashback. Try using a different connection to the same device or contact your provider to see if it has anti-ad tracking filters on your call.
Internet network:
The quality of the Internet connection, such as unstable Wi-Fi or mobile data (3G, 4G), can affect the activation of cashback. Corporate network configurations such as proxy servers, VPNs, or advertising website locks can also cause problems.
Business partners:
Sometimes the seller may have temporary problems on his website that prevent the activation of cashback. Try activating cashback with several other merchants to confirm if this is the cause of the issue.
