I am trying to watch Apple TV Plus on my browser since I am not upgrading to Catalina, and I want to watch it on my PC as well. However it is very buggy, and when I click to watch a episode, it asks for my address and credit card number. However, I paid for Apple TV Plus with a Apple iTunes gift card. As such, when I close the dialog asking for my info, it just shows a black screen with a x button. Clicking on it does nothing. This repeats over and over again.
