What browser did you use to access the apple site?
Make sure that it is a secured browser like firefox, or chrome.
Make sure that you are not a limited. If so go to paypal resolution center.
If paypal suspect someone could be using your account without your knowledge, paypal will limit it for your protection and look into the fraudulent activity. Usually, paypal will ask you to complete one or more tasks to remove your account limitation.
paypal will also limit your account if your debit or credit card issuer alerts paypal that someone has used your card without your permission. Similarly, if your bank lets paypal know that there have been unauthorized transfers between your PayPal account and your bank account, your PayPal account will be limited.
Another reason why your account could be limited is seller performance indicating your account is high risk. For example, receiving an unusually high number of claims and chargebacks from your buyers is an indication of poor seller performance. If you start selling an entirely new type of product, such as a higher-cost item like jewelry, or if your typical sales volume increases rapidly, your account may be limited while we do a review.
