Doesn't matter which payment card, balance or whatever
The payment selection is broken on macOS
The dragging mouse cursor symbol will appear when you hover over it, but you can't drag the payment methods
If only works if you try it like 100 times, sometimes it moves and snaps back
99% of the time nothings happens at all
I tried different methods, mastercard, amex, paypal etc
Doesn't make a difference
But it works on iPhone
To be honest the App Store on macOS is really buggy
(If you move the App Store window between 2 identical monitors the window automatically resizes to wrong dimensions etc things like that...)
I guess you can't do much about it besides bug reports and use the iPhone payment settings
The payment system for app purchases is flawed anyway
Whoever decided that only the first payment card can be used for App Store purchases needs a basic course about modern economy and fintech lol
Imagine the struggle I have because I need to change my payment method every single time just to separate my private and business purchases
On top you got the apple care subscriptions etc also running on the first payment method
So you always need to change cards at the right time, to prevent accidental subscription payments on the wrong card
It's a mess...
