When I add my card it says I already have that payment method?
I’m having the same problem . My problem is , when I add my card it says I already have that payment method on file and then when I try to click on that payment method it just says “payment information” and says something in red .. I go to remove it to add it back again but like you said , if you have an active subscription you can’t . So I removed ALL my subscriptions and it still says there is one active .. I was assuming it was my iCloud+ for storage so I go to downgrade and it stays at the 2.99? Apple is starting to be a scam . Oh and when I add a different card , right away it tries to charge 17 for HBO but THEN I add 17 to my card and try to reuse that payment method AND IT STILL DOESNT WORK !!
