>One thing to note, and maybe another anon can explain why… Sometimes the url from the address bar works but sometimes it doesn't
You have to strip out the garbage if it includes stuff like a time stamp.
Here's an example of a good link
https://www.youtube.com/watch?v=yZG_0iuCVs4
This is a standard start to a youtube link:
https://www.youtube.com/watch?v=
This is the identifier (or serial number) for a particular video
yZG_0iuCVs4
Anything else in there, with more question marks, t= for a timestamp, etc., will keep it from working
You can even post shorts if you replace
https://www.youtube.com/shorts/
with
https://www.youtube.com/watch?v=
