I've been trying to connect my PayPal and/or my credit card to my account by have had no luck with either. If it helps at all I just turned 18 a week ago. Other than that, my PayPal has a credit card attached to it, a positive money balance, and my bank account has a positive balance. If this questioned is answered elsewhere feel free to give me the link that way I don't waste anyone's time. Also, this is the message when I get to the final stages of connecting my PayPal account:
The reward method you chose is not authorized. Please use another reward method to request your cashback reward. If you get this message multiple times, contact customer support.
Any help would be greatly appreciated. Thanks!
