Constantly losing pedal resistance, power, cadence and heart rate info

Hi all,
I am new to Zwift and recently purchased a Zwift Hub One with the virtual gear change, the issue I am having is when in an event/race it starts off by losing any resistance in the pedals and spinning out. Then the wattage, cadence and heart rate monitor reading in the top left of the screen zero out and the aviator stops even though I’m pedalling. This happens several times in during an event and sometimes I get left on the start line. I use the companion app, blue tooth and a lap top to run it and everything seems paired up ok. Thanks Roy

Are you pairing the trainer directly to Zwift, or pairing via the Companion app? If you’re pairing directly to the laptop, try pairing via Companion and see if that’s more stable.

Thanks Paul I will try that
