Update*****
I just put the iframe in by itself and it comes up with that.
So, maybe it’s nothing then.
It occurs, pops up, that error message when the mouse is hovering over the iframe.
<iframe width="277" height="207" src="https://www.youtube.com/embed/jMAShwisnQI" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
It also occurs on YouTube’s own website. So, it’s definitely not something to worry about. That’s something they have to fix.
If I’m wrong let me know.
