Youtube Videos Won't Play on Mobile

Hello,

I have two YouTube videos embedded on my site at www.sunnybranchwealth.com and www.sunnybranchwealth.com/our-work-together. 

Both videos play fine on desktop. When trying to view them on my iphone (8+ running iOS 16.0.2) I can see the video thumbnails and the "play" button but nothing happens when I click. Have tried in Chrome and Safari, with cookies cleared in both.

Suggestions or troubleshooting ideas welcome, thank you!
