My Apple Card limit was reduced to $300

If your credit limit was reduced on your Apple Card Mastercard issued by Goldman Sachs Bank there can be multiple reasons. The most common is you weren’t utilizing the credit limit assigned or you requested ( if you asked for a credit limit increase then failed to use it). Another possible explanation is an issue with the account such as frequently being over the assigned limit, or having multiple late or missed payments.

If none of the frequent causes above happened with your account you’d need to provide more details. These are public forums so please do not include any publicly identifiable information.
