Bluetooth remote not responding when Internet is down

Dear,

I noticed that the Bluetooth remote is not responding when my internet connection is down and the light is still connected with my WiFi network.
Is this by design or a bug ?

Remote could work, it has nothing to do with internet connection. Please double check it if it is in low battery.

@dingyichen I have the same issue. If the network has problems than the light is not responding to the remote.
I got the remotes only working by blocking the network connection in my router and use local API and Bluetooth.
