I am trying to subscribe to Friends. When I enter what plan I want, name, billing address and credit card information then hit subscribe and I get a message that, "Your postal code is incomplete". I put in my full address but still get the same message. I tried to send an email to "Contact Support" but when I click on that nothing happens. So this is the only place I seem to be able to do anything. I tried Chrome, Safari and Brave. This is on a Mac. How the heck am I supposed to subscribe?
