I can help make sure you're able to update your subscription.
Have you tried updating your billing information in the private browser? If not, I'd suggest doing that first. The incognito window does not store any data in the web cache and disables browsing history, making it a good place to isolate browser related issues.
Here's how to switch to private browsing:
Google Chrome: press Ctrl + Shift + N Mozilla Firefox: press Ctrl + Shift + P Internet Explorer: press Ctrl + Shift + P Safari: press Command + Shift + N
If you're not getting the same behavior after switching your browser, you can go back to the regular window and clear your browser's cache.
However, if the issue persists after the steps, I'd recommend getting in touch with our Online Care Support. There they can check your account and help you update your billing details in a secure environment.
