You can't send YouTube Videos in PM right now.
It goes through as a blank line.
I noticed it last night when we were setting up Movie Night.
And we checked today - still doing the blank line when you try to send a link.
We did send links to other things on the net today without issue.
Photos are going through ok too.
Maybe it's a response to people sharing material like the live streaming of the New Zealand massacre.
Gees I hope folks are better than that here. I know there was a problem with that being shared on FB - but they did get a team on it.
Apparently one of the gunmen directly downloaded it to social media.
