Is there any way to have have store credit used before charging card?
I am the primary account holder for my family sharing group. I have over £200 of store credit which is used when I buy something on the App Store. However I have just noticed that purchases made by my family members are being charged to my card when I still have plenty of store credit.
What is the sense in that?
Is there any way I can change this behaviour?
thanks
