I am very new to Captivate and have just created my first course with multiple choice quiz. When I click preview - live preview on all devices. The quiz works fine on the desktop but when I QR scan it on to my iphone and put in the correct answers it always comes up with a quiz score of 0. Some colleagues have tested it too for me and it still comes up with 0. Any ideas on how to fix please? Using Captivate 2019 and have created a responsive project.
