@ben @jess Is there any way to embed mux video player in dev,to post itself ? i am not able to find liquid tag for that

Hi Jess, unfortyunately, while working on the current MUx DEV Challenge it appears the embed does not work :

Below the code :

stream.mux.com

And the video is here : player.mux.com/02sUXDw3XC3WkSDfzO2...

Nice update. Being able to use YouTube, Twitch, or Mux links as cover videos makes posts a lot more eye-catching, and it’s great that it works just by pasting a URL. This should be really useful for tutorials or project demos, especially with the Mux challenge going on.
