That morning, I realized that the Spotify player was no longer embedding on my Wordpress site, when I put the link in the Gutenberg block.
I thought it was just me, so I uninstalled some plugins, checked the code and nothing. Later, I looked for other Wordpress sites about music, and saw that they face the same problem, and are no longer embedding links.
PS: the HTML solution "<iframe" works, but it is a bit more laborious and boring.
