i can see on the code that you used WYSIWYG when i wrote in the rules not to use it! :'>  WYSIWYG adds and deletes a lot of complex coding such as icons and music players

i suggest having a read of how to do that properly here (though if you are a mobile-only or do not have access to a phyiscal keyboard, you could skip enabling Code Editor); i would also recommend restarting the code just so you have less of a chance breaking it BUT if that's a hassle, you can add back the music by deleting the <span> around the <iframe>

<span class="fr-video fr-fvc fr-dvi fr-draggable"><iframe src="https://www.youtube.com/embed/https://youtu.be/0V84KclH62U?controls=0" class="w-100" style="position:absolute;top:-140px;left:0;height:400px;opacity:.001;" frameborder="0"> </iframe></span>

you'd just have to click on the progress line thing in order for it to play, since there's missing icon decor... also! the youtube video itself does not work (some videos do not allow embed play </3) so you may also want to choose a different video!

hope that helps! ^^
