Users should be able to use Mobile Devices to complete courses in the LMS. In the event a user is having issues while using a mobile device, kindly suggest that the user switch to a desktop computer/laptop and troubleshoot accordingly. 

I see that you are currently using a mobile device to access the LMS. While mobile devices are supported, I'd like to ask that you switch to a desktop computer while we troubleshoot the issues you are having with this course.
