There's no message in the logs. Out of boredom tonight I was poking around between two nearly identical Pico controllers and I see this in the Application State of the button controller I can't edit:
Now this is especially odd, because none of my other button controllers have this. I have two other Pico controllers, and they both show this instead:
All other values are exactly the same, or different in exactly the way I would suspect. So I'm guessing these values have something to do with why BC is unhappy with this.
@bravenel any way for me to clear those values, so that editing this Button Controller is possible again?
Since the 2.20 update I have two picos with this app error. One that I can edit as expected. The oldest one is listed under Button Controllers the the other under Rule Machine. The newest, only a few weeks old is under Rule Machine and correctly accessible. They all operate correctly and don't throw any odd entries in the logs.
