I am using the PayPal mini-browser to complete chained payments. I have this up and running in desktop Chrome, Opera, IE11, Firefox, Edge, and Safari mobile using the minibrowser. My problem remains with Chrome in a mobile browser. Mainly, after completing payment, I get a returning message but the loader just spins and the minibrowser never closes. When cancelling payment, I get a message saying "Just a moment-this window will close automatically." Then the window never closes. What can I do?
