Asda rewards says I have £57 in my cash pot. I go into the app in the “spend section” to create a voucher. When I then select the amount of the voucher I want to create it won’t let me. The numbers are all greyed out and won’t allow me to select them, it just doesn’t do anything. The vouchers are in date so I am really confused as to why I can’t create a voucher for my online order I have booked for this week. Can anyone help?
