Embedded video rich text block not responsive

Hi there!

I’ve embedded a video on a blog within a rich!
text block but the video is coming uit waaay wider when I view it on Iphone. Is something that I should fix with custom code ?

Many thanks in advance,
Paulien

Did you use a custom code embed Or did you select the media icon and inserted the video that way?
