How long does it take for a check payment to Apple Card to post to the account? This payment check was cashed by Goldman Sachs Apple Card (I have the check images) 8 business days ago?

Hi, the Goldman Sachs support team will tell you to allow 10 business days for a payment on your account by a check to be credited to your credit limit.

The Apple is unique and muguy is correct in his statement that payments via your banking accounts made through your iPhone or online will be credited much quicker. If you pay via Apple Cash your account is usually updated instantly.

No idea. Payment is intended to happen through the Wallet or online at card.apple.com instantaneously. You would have to contact support if you managed to send a paper check somewhere.
