2 KS230 3-way circuit's each installed each with 8 LED's. They do not blink on the highest setting.

I have a third 3-way also with 8 LED's and they blink (on, off, on, off, etc.) only on the highest setting.  Changing the dimmer down a notch stops the blinking.

All of the LED's are the same, installed at the same time from the same manufacturer.

If the app has a "mex brightness setting/calibration" that would potentially fix this.
