Workaround:
- Unplug ATV
- Launch running phone app or running watch and let it find/lock on Stryd
- Fire up ATV and then Zwift
- Pair your power source, controller, cadence etc. to preferred sources
- Start the Ride
The idea is that Stryd can only connect to one BLT device at a time. Lock it up with your running watch so APTV can’t grab it. So far this has worked for me. Not great, but at least it puts my KICKR as the only pairing device.
