it says there is somthing wrong to take the money back to my sender, so it returns to my account, but i didn't find $1 waiting for approve again.
Paypal is always mysterious and they say one thing and do one thing. In my case, they are asking me to remove my bank account details after disabling the "remove" button. So it's paypal nature to play double game. The only way to solve out paypal issue is to call them directly via phone. If you send them support ticket, they won't respond to you.
