TIDAL Embeds broken

The plugin https://wordpress.org/plugins/embed-tidal/ mentioned in the other topic is much too old for this. It will not work. You could of course contact their support and hope that there will be an update.

Alternatively, you can also mention your wish to the Gutenberg development team. Create an issue here: https://github.com/WordPress/gutenberg/issues – currently there is no issue for Tidal, neither open nor closed, which is probably why it has never been an issue there.
