Can't use Apple ID balance to buy app
I tried to buy an app to use up my credits in Apple ID. There are 10 Euros.
I got into this page asking me which method I want to use to pay.
I picked Apple ID.
Then I got to this page.
two options showed up: redeem and add fund. No option to use the balance to pay. I don't want to redeem nor add fund.
Not really sure where I should tap to make payment.
the redeem page is like this:
I don't need to redeem as I want to use my balance 10 Euros.
Any suggestions?
