When a Zip subscription card is added to a service it will remain in a pending state until the first recurring payment runs.
In most cases the payment will run at the time the Zip subscription card is added, however this may not be the case if you have recently paid your subscription using a personal debit or credit card.
For example, you recently paid your Netflix subscription on the 1st of March, and today you decide to update the payment method to a Zip subscription card. The next billing date is not until the 31st, meaning the newly generated card will remain in a pending state for the next 26 days.
