Issue description:
My event calendar won’t display on the desktop (Chrome or Edge), though it’s fine on my phone (Safari).
For this page I’m taking a duplicate of the widget displayed on another page and adjusting the layout. I then copy the embed code into the page in question. It worked well in the past.
I tried embedding an URL rather than HTML. That worked. I’m not sure why. It may have something to do with my home network aggressively blocking what it see as threats. Anyway, the problem is solved for now.
