Of course, you’ll always be able to change your payment method.
To do so, log into the platform, and access the page dedicated to your sub by clicking on the arrow near your name (top right corner of the page) and then “My subscription”.
Click on the current subscription from the menu on the left, and then go to “Payment method”.
There, you’ll see your current payment method, and next to it the “Update your billing” button.
Click on it.
A pop up will appear, where you’ll have to insert all your new payment information.
When you are done, click on “Save”.
Pretty easy right?
