When I test it using Reflect is also plays fine. But it does not play on my site.
I do have it in an iframe with some wacky styling to get it to be responsive:
<iframe style="width: 1px; min-width: 100%; height: 100%;" src="https://www.yciw.net/_1d/" width="100%" height="100%"></iframe>
I'm testing it on an iPad mini running the latest iOS
UPDATE: when I load the site not in the iframe it does play as expected. I really need to have this iFrame be responsive and so far this whacky code is only way I can make it work. Does anyone have any insight on how to restructure my HTML to make it functional?
