Is anyone else experiencing issues with videos in DomainAcademy Course? (DNAcademy)

Videos in this course are playing with no audio! I have been experiencing this issue for two days now. I also checked on other devices to make sure it's not my device issue, but the problem persists. I was trying to find out if anyone else has reported this on Twitter but I don't see anyone talking about this! Could someone with the membership please check and let me know if it's just me?

I have raised a support ticket with Godaddy support... initially, the support guy didn't know what DomainAcademy is and then I had to explain that I have an active DDC membership and bla bla bla...

Hope this gets resolved soon.
