This app is utter garbage. The controls are unresponsive the majority of the time and when they are, the new setting just reverts back to the previous in a few seconds. The "fix", it seems, is to delete all bulbs and reconnect. This is inexcusable. Don't buy any bulb that uses this app for control Day 1 of documenting how often I have to reset my bulbs in order for the app to see them. THIS HAPPENS DAILY.
