Hey Charles,
For the past few weeks I haven’t been able to watch videos in embedded tweets.
Other, non-tweet associated, videos play fine. gifs in tweets play fine.
If I open the tweet in a separate tab, not associated with LGF page, the videos play fine.
When LGF is viewed in Chrome, the video just shows it is endlessly spooling. Using Firefox the video window shows black with a “This media could not be played” message.”

Like I stated, if I click on the the tweets timestamp, in either browser, and open the tweet in a new tab, the videos will play fine.
