"Get £10.00 off when you purchase in our app!" discount

Hey, I keep getting a popup saying 'Get £10.00 off when you purchase in our app!' saying it expired in 5 days. it doesn't give a voucher code so how do i get this discount to apply to my app order?

1. Open the camera app on your phone
2. Scan this code with your phone
3. Go to the app store and get the app
4. Start saving!

those all all the instructions it gives.

for anyone also having this issue I finally managed to get the code to show up on the app by reloading the app a bunch of times.
