Dimmer Wall Light Switch stoped response

I’ve got Yeelight Halo LED Ceiling Light 470 (YLXD50YL) working fine on firmware. Recently i bought Yeelight Smart Bluetooth Wireless Dimmer Wall Light Switch Remote Control (YLKG08YL) and after rough pairing proccess it all work fine until now. Now, when i tried to press the button or rotate it - nothing happen. Lamp brightness or power switching could change only after 5-10 attemps. Lamp interaction via voice or phone app still works fine. I’ve changed battery and re pair both devices, but again, nothing happened. Distance between these devices is about 1.5m. Again, everything used to work fine until last week. Any ideas?!?
