I am having trouble launching QRTEngine. Yesterday, without changing the code whatsoever, sometimes when I launch the Stroop tutorial, the preview is in the Qualtrics layout and leads to a number of issues; other times, it launches with the QRTEngine banner and works fine. Today, it always seems to launch in Qualtrics. The problem is consistent across different operating systems and browsers. I am wondering if other people have experienced similar issues? Any suggestions would be much appreciated!
