Updating your credit card information
You can update your credit card information in the Drive Connect app by following these steps:
In Salesforce go to the Drive Connect app under the App Launcher.
Click on the first step called License & Permissions under the setup tab.
Click the Manage Plan button and on the next screen you will see at the button of the page a Payment Method section which contains the last 4 digits of your currently tied credit card as well as a button to cancel your subscription.
Under the Payment Method section you will see a pencil next to your credit card. Click it to edit your card information.
Once you have reviewed and updated your credit card information you can hit save to be taken back to the Payment Method section.
You will now see that your updated credit card information is updated under Payment Methods. You do not need to update your plan for the changes to go through.
