@Techaltar @thibaultmol Not sure about the over/under on a decade, but I was removing those source identifier keys back when I ran a business’ social media account back around 2018. A lot of people bypass the issue by grabbing the URL straight out of their browser, but I sometimes use the time key to have the video start at a specific point, and using their share function is quicker than manually calculating and adding it to the URL.
