As of today (Sept 6th), my HS220 wi-fi dimmer responds EXTREMELY slowly when turning on/off or dimming up/down. I removed the device entirely and reinstalled via the app, but problem still persists. For example, when I power OFF, it typically takes ~3 seconds to fade off, but now it takes almost exactly 3 minutes (I timed it). It only begins to fade off at about 1.5minutes. When I power ON, it typically takes ~3 seconds to fade on, but now it takes almost exactly 3 minutes (I timed it). It only begins to fade on at about 1.5minutes. When I change the Brightness using the wheel on the app or the preset dimming percentages (i.e., 25%, 50%, 75%, 100%), it typically responds immediately, but now it takes almost exactly 3 minutes (I timed it). It only begins to fade on or off at about 1.5minutes.

Clearly some sort of Kasa programming/software update that needs fixing please.
