I've tried about a dozen times to update my payment method for renewing my Realms subscription and I keep receiving an error stating my info is incorrect. I can assure you that my card number, exp. date, ccv code, state and zip code are all correct.
I've also tried replacing my payment method for my Mojang subscription and I get the same error message.
Please advise
