Accordions stopped working

One instance of Accordions plugin started failing on my site.
I have 2 instances running, the first is just under the header: "Who We Are"
The second is below that, next to "Upskills Courses" on the right. It used to work, but now just shows 3 flashing dots. The embed code is correct. Any suggestions?

I also submitted this question to support last week but received no reply. Is support reliable for this product?
