George, I don't think you need to use the embed button in the reply window, just check 'Message is in HTML'
and copy the code from the share button on YouTube.
Of course this leaves you having to write out line breaks because the return key doesn't work in HTML, and I didn't do that because phone keyboards are abysmal for that stuff.
