I am having issues when doing a solo or group workout. I will be riding and the watts will fall to zero. Typically the Game screen will freeze first and then a few seconds later the watts drop. The other issue is when I pass under a banner for the next segment of the workout, the watts do not change to the new watts indicated in the workout. A few seconds after that happens, the watts will also fall to zero. I am using a PC and connect to the Wahoo Kickr using Bluetooth. Any suggestions? I have reloaded Zwift and checked for any computer updates.
