I have over 200 bricks but when I want to add lives it will not let me. Now on my I pad I can but not on my laptop? Also I can make purchases on my Ipad but not on my laptop. How can I change my billing info on the laptop.
First the billing info. On your iPad it's Apple that handles all purchases through your Apple-ID and on Facebook it's Facebook that handles all purchases through the payment options that Facebook provides in your region (payment options vary between countries). Check this page for payment details and options on Facebook.
Does the issue happen when you try to buy more Lives with the Gold Bars on your laptop? Do you get any error message? What exactly happens or goes wrong?
