Hello @zhangqing9029 , Thank you for contacting us!
It is entirely possible that you could be running into our security system. This would have temporarily prevented you from taking any further actions in your account. Although our security practices and transaction reviews are meant to protect all customers, sometimes they affect an account in good standing. In this case, I suggest you try again after 48 hours.
Please be noted, if we try to attempt again before 48 hours then the security algorithm may reset itself and the same situation may occur again. This will result in a further delay. Therefore, I would request you try using a different source either a bank or card or wait for 48 hours time from now then try again. Your kind understanding is much appreciated.
If you still encounter the issue, I'd recommend reaching out to our Customer Support teams by clicking "Contact" at the bottom of any PayPal page for further assistance.
Regards,
Becky.
