I think this is a known bug, but I wanted to ask the status of this feature for the Beta. The spindown on my '17 Snap through Zwift fails everytime (stick at 1 mph). Samsung s8 device. Zwift is typically stable outside of this issue (assuming I stay in the app).
The work aorund is to minimize zwift and open the Wahoo app. This disconnects bluetooth and causes a cascade of problems trying to reconnect devices post Spindown (Wahoo HRM and BT cadence). Often times I am running late to race and cant connect the devices in time.
