Video on a video slider doesn't play on mobile

I just purchased another 6-month support service.

I know I am using an old version of Canvas template, but I hope you have a solution for this issue.

Recently built a site, www.seattlemaxicourse.com, and there's a video slider on the main page. The video slider works okay on desktop, but it doesn't play the video on mobile. Only shows the poster image, How do I fix this issue so that the video plays on both desktop and mobile? Below is the code for the slider. Thank you so much!

I see that you haven't responded to the tickets from 8 months ago. Do you no longer provide support for this template?
