Comment 3 Nate Graham 2024-03-07 19:33:54 UTC 
Maybe Spotify doesn't expose this functionality to us but we don't have a way of disabling the UI for it?

But in Plasma 5 rewinding worked, in Plasma 6 - no

I can confirm this bug, and it isn't just Spotify that is affected. Anything that exports an MPRIS interface is unable to seek using the Media Player widget.

Please report the bug to Spotify if the slider works for other players
Comment 8 Fushan Wen 2024-03-11 08:49:06 UTC 
No problem with Audacious, Firefox with pbi and VLC, so it's likely a bug in Spotify.
Comment 9 AlexDeLorenzo.dev 2024-03-11 10:45:17 UTC 
On my end, it looks like the Media Player widget isn't calling `org.mpris.MediaPlayer2.Player.Seek()` or `SetPosition()` via D-Bus. 

Other MPRIS clients like `playerctl` can successfully call the `Seek()` method without a problem, and successfully seek on media players.

It's not just Spotify with this problem, I cannot with seek with the widget at all with any media player.

libkmpris: work around nonstandard players

Some players return strings for mpris:trackid, which does not conform
to the MPRIS2 standard. This adds a workaround to not let the behavior
affect the position slider because setting position requires a track id.
FIXED-IN: 6.0.2
