Very interesting discovery:
I was finally able to get the Windows app (4.1.1) working again (Windows app is not working anymore - #7 by srudin) and saw this:
Compare this with the same view in the Android app (4.0.3):
As an example check out the room “Gate”: You can see that the Windows app shows the “desired” behavior with some colored background for white lights (as it was with API V1) while the Android app shows the black background as complained above. Both screenshots were taken at the same moment and showed this situation over more than a minute.
@Thomas Thank you for the white color fallback fix (although I haven’t received it yet) but I wonder why the fallback is necessary at all if the Windows app can handle the situation properly?
