Login makes no sense; cant find subscription options

i wanted to log into my avast account with the credentials of the email i bought the subscriptions with so i can adjust billing info and check which card i used because i forgot.
i can see the subscriptions in the desktop app (vpn and premium security) but cannot see the subscriptions on the website.
i dont like it, and im tired of how difficult everything is. I have autism and i have a premium account, it should absolutely be easier than it is now

Have you checked here:
https://subscriptions.avast.com/

Hi,

If I am correct, you have two email accounts with us.
xxxx@gmail.com and xxxxx@comcast.net
To view your subscription details for non-mobile applications, you need to create a my.avast.com account for your email address xxxxx@comcast.net or you can log into your existing avast account and add xxxxx@comcast.net as a secondary email address.
Please see this FAQ more information: https://support.avast.com/en-ww/article/Account-FAQ

To make changes to your credit card details,
please go to the avast store (https://www.avast.com/find-order) and enter your order id and password.
You’ll find your order ID and password in the order confirmation email we sent you (they’re different from your Avast Account login).
Please see this guide for steps on how to do this. https://support.avast.com/en-ww/article/182/
