Q.r. Codes

[No-Puffin]

For some time I have used Subway and complete the survey to receive a free cookie. All has gone well but..... for some reason the QR box code is not how showing when I use my desktop in order to print the necessary information in order to get the free cookie. It shows on my tablet but I can not print from tablet. Can anyone help. Any information to be U.K. related please.

Have go got any ad-blocking software running in your browser? (e.g. AdBlock Plus). If so, try disabling it and refreshing the page where the QR code should appear.
