What happens to auto top-up when I add a new card?

Adding a card from the auto top-up sheet automatically enables auto top-up with that new card. If you start setting up auto top-up, enter valid amounts (at least the $10 minimum), and then add a new card, Playbox turns auto top-up on using the freshly added card and saves it for you. If you cancel the add-card step instead, the sheet stays open with your data so you can finish manually. If a later charge fails (for example the card expired), auto top-up is turned off and you’ll see a notice asking you to update your card and switch it back on.
