I found out that you could watch Facebook videos and it worked once, but then I tried on my cell phone to watch certain videos with my friend and it says “video unavailable”, what can I do to make it work again?
Can you share a link that you are trying to play in your room?
I want to see this video

This seems to be a limitation of this specific video. Not all videos from Facebook can be embedded and played I other websites. I tested some other videos and they were working fine.
