How can I link additional payment cards to the app?

You can add additional cards to the app by going to Settings > Payment Methods > Add a new card.

To add additional cards directly from the payment screen of your app, simply tap on the switch arrow next to the card which is already linked to your app.

Once added, the card will be visible in the payment section of your app and under Payment Methods, alongside all of the other cards which you have linked to your app.
