@VisualStuart In fact, delete everything that comes after /watch?v=[string of letters, numbers & maybe dashes]

How do you know when that string ends? Because it's ONLY letters, numbers & dashes; you start deleting as soon as you hit a question mark, ampersand or other special character.

The only time to not delete everything is if you've chosen to share including a time code. In that case you can remove ?feature=shared from the URL, that's also a data point (though not an identifier) 😊
