I have put in a similar ticket. I believe what is happening is that the Smart Lighting app is tracking the status of the light within its own context. So each child instance of the smart lighting app would work if it was the only input to the light. If you use another minimote to change the state of the light then the first minimote is out of sync and can take some clicks to catch up.
You don’t even have to use a second minimote to cause the problem you can do it by turning the light on with a routine and then it will take more button clicks to get to turn off with the minimote. Once I realized this is what was happening the behavior of my minimotes was at least explainable.
Hopefully an update to Smart Lighting will be updated to fix this behavior.
