It looks like the Spotify apt repository hasn't updated since last July. It has version 1.1.10 in it. The Snap store has 1.1.26, but I can't use that on my work machine due to our software policies, while we have a mirror of the Spotify apt repository which we can use. Though, that's also a bit old, last updated in February, while MacOS is up to 1.1.33.
Will the apt repo be updated again? I'd really like to have the disable Automix feature in my client.
