Where can I find a way to update the credit card I have on file with RHP?
You may be able to click on the star by your username, which will take you to the page where you can click on your payment method, and from there you should be able to update your card info.
Best advice is to just send feedback to get help with this. 🙂
If your subscription payment is processed by Stripe (rather than PayPal) then you will see a "Manage Billing" option next to your subscription on the My Subscription page.
