Thank you so much for taking the time to check this for me and help.
It does appear to be a caching issue, I believe. The video embeds do appear in some browsers and incognito screens. I’ll need to be patient and troubleshoot through this while editing. (I did enable Development mode.)
I am new to using Cloudflare (less than a week) and I wanted to be sure I didn’t miss a setting I needed to revise or activate.
Try clearing your browser cache. Especially if you already purged the proxy caches, we can probably safely say it’s not a caching issue on Cloudflare’s side.
