Hello there, ahmedh,
When updating your billing information, make sure the payment method you enter is supported. These are the accepted cards Visa, MasterCard, American Express, and Discover. The card must have a US-based billing address.
Here's how to update the billing information:
- Click the Gear icon.
- Select Account and Settings, select Billing & Subscription.
- On the Payment Method section, click Edit.
- Enter the complete credit card info then select Confirm card.
- Click Save Changes.
If you'r subscribed through the app, check this article on how to update: Update the payment information for your subscription. Scroll to the section I subscribed through an app store for the detailed steps.
If you need anything else, please leave a reply. I'd be glad to help you more.
