I KNEW I should have just went to the paypal site and not used the app. I have never used the app before, so I thought I would give it a try, but I figured something would happen. I sent money using the app, and I got a confirmation at the end saying my money has been sent, but the seller says he hasn't received it, so I checked my account and there is nothing, as if I never sent it. Now I don't know if I should send the payment again, for fear of having two payments sent. Have any of you used this app? Does the seller eventually receive the money?
