As the title say I am trying to make a payment using my PayPal account but without ever opening the PayPal website is says “check required inputs”. I do not see any inputs much less ones that need/should be checked. When i try to pay with my CC instead it says “the card is expired and has been removed” which it definitely isn’t since it expires in 2028 and actually hasn’t been removed from my account. I have tried this on Zen and Firefox and received the same result.
You could try to logout of the store, close your browser/clean browser cache and retry. Other than that only a support ticket might help you.
