Can't play YouTube video through iframe API when video is unmute
"player.play()" doesn't work on latest version chrome, we can solve the issue by adding the allow="autoplay" attribute to your parent iframe
To know the root cause, you can check: "What's changing?" @ https://developers.google.com/web/updates/2019/01/user-activation
You describe the new Chrome behavior.
You now have to click into the iframe manually - either to start playing or to unmute.
To use "autoplay," you have to use "mute" as well. Make sure not to disable "controls," because the user has to click the loudspeaker symbol to enable sound.
