Similar for me, this “update” is still showing the bug introduced in May ?
Apple TV. Garmin V3 pedals, Polar HRM, Kinetic Road machine Control, Companion App iPhone 6s
Need to re-pair trainer for Power from Trainer first, then select V3 power pedals second for power and cadence
If I pair V3 pedals ( with are remembered on boot by default after boot) the trainer is NOT shown in the control section despite several minutes wait.
