I have noticed that one boxes do not work for youtube. They did on the previous forum. I don’t know if that can be fixed or if the new forum settings are different and won’t permit it so just asking. The first couple of posts in the music thread both have links that can’t be one boxed. I tried different things. Interestingly, just copying a TSN link via email no longer one boxes that link, but I discovered that if you click on the icon on the white bar that comes up it changes the link to a one box and the printing from red to black in the link- that is how you know it will be one boxed.
From where? I always hit “copy” under the “share” button in the link and when that didn’t work I emailed the link and copied and pasted it but no go either. Maybe others have done it, but I have seen a lot of youtube links not one boxed so I’m guessing that others are having similar problems.
