I would suggest waiting the full hour but maybe a few minutes longer then try using the phone app to change it. Here's how.
How to change credit card on phone app
Download the app from the app store if you already haven’t.
Sign into your app.
When your app opens you’ll be in the My Account tab. You will see a plus button at the bottom left above the My Account tab. Click on it.
Once you’ve clicked on it, go to Payments
The next screen you’ll want to click on Manage Subscription.
The next screen will give you the option to change your credit card information when you click on Manage Payment Method.
There you will be able to enter a new credit card and expiry date. Click on Save and you're good to go.
