Don't know what's going on, but I am no longer able to turn off Osram Lightify Bulbs from the Dashboard. They turn off from the device page with no issues.
When I use the Dashboard, they simply turn back on again when I exit the bulb popup.
I'm not good at explanations so I made a video.
Cat Light is a Osram Lightify A19. Living Room is a group of 2 Osram Lightify A19s.
