Yeelight remote controls disconnecting.

Hi. I have 5 yeelight ceiling lamps on one floor. Each is connected to two remote controls - one handheld remote which it comes with and one bluetooth round knob remote sticked to the wall. Often is happening that both remotes would disconnect from the light and i cannot control it, only from the app. Untill I phisically turn off and on the power to the light. Then it works again. And this is happening on all the lights. They are all on fw. 2.0.6_0026
Any suggestions how to fix this oncefor good? Its quite frustraiting having to do this almost every day.
Thanks in advance.
