Nanoleaf Group Scenes and Matter

When is Apple going to update the HomeKit's Matter package to accommodate group scenes? Very frustrating that the implementation isn't complete — and it's been like this for months. (It's the problem behind this question, for instance; I am experiencing the same thing. If you create a color-changing scene in the native app that includes Matter bulbs, it will appear in the Home interface but the color pops to something random and stays there. Running the scene on the native app works just fine.) These bulbs are being sold in the Apple Store even now, and they don't fully work with HomeKit. Has anyone heard anything?
