In order to update payment information, view your billing details or download historical invoices you will need to go to settings within Schema App. From there go to the "Plan and Payments" tab. 


There will be a chart on the bottom half of the screen with a button for "Card and Invoicing Details". Click here. 


You will then be taken to a new window where you can navigate to the desired tab. 


If you have any issues with this process please reach out to support@schemaapp.com
