The problem with the tap is that out of the box it’s not an always listening device. That means it can’t be synchronized because it needs a button push to wake it up.

Mine is always listening / wakeword activated… I don’t think I needed to do anything special to activate that; just an automatic OTA firmware upgrade, I think…
I think it’s more likely to have to do with network management. The other distinctive feature of the tap is that it’s mobile. At this point, all of the other echo devices have a known physical location. That does a number of different things, but as Sonos demonstrated, it’s critical to synchronization of music. Otherwise you get that issue where the same song is playing but just slightly off from the one in the next room. There’s a lot that goes into keeping everyone in sync, and knowing where they are is part of it. But I’m just guessing.
