Why can I not see the YouTube thumbnail on the forum I belong to when viewed on my Mac Mini, but I can see the thumbnail if I view from my iPhone or iPad. MacMini Late 14, Safari 15, Big Sur.
Why can I not see the YouTube thumbnail on the forum I belong to when viewed on my Mac Mini. All that's there on my screen is a blank space.
The other forum members can see and play the video that I've posted
But I can see the thumbnail and play the video if I view from my iPhone or iPad or another browser on the Mac.
I'm using a MacMini Late 14, Safari 15, Big Sur 11.6
Mac mini, macOS 11.6
