Connected But No Signal

When using zwift Wednesday I noticed a lag of between 10 and 30 seconds from my kickr to adjust the power in erg mode.

This evening I noticed the same lag.

Then it stopped working completely. My avatar stood there on the side of the road.

Under bluetooth it showed the device connected but no signal.

I reset the power supply to the kickr but did not resolve.

Eventually I quit.

I shut down all other apps before zwifting.
