Hello @srudin, thanks for letting me know. This is definitely a bug as this is not how it is supposed to look. There should not be any colour changes in the new version. Apologies for the inconvenience caused, would love to get this resolved.
I am unsure what is going on. On my system all works fine, and you are the first user to report this.
In the update we migrated to a new API (= communication with the bridge), as Philips Hue no longer supports the old method we used (which could suddenly stop working). I think something is going wrong with this new API, maybe the scenes are causing the issue. Does the issue only happen with a specific scene? Or does it also happen when setting the light colour manually using the colour picker?
If you still have the official Hue App: could you please check if the same issue appears there? So at least we can rule out that this is bridge error or a corrupt scene. As Hue Essentials shows all the rainbow colours, which it reads from the bridge, I think something is going wrong on the bridge itself.
This was always the case, no changes here. However, a room should never appear as black, which means something is wrong.
Also unable to reproduce this unfortunately. Any chance you could share a screenrecording which shows the behaviour? That would be very helpful, thanks in advance.
