I have a new wattbike proton.
The wattbike hub app running on android tablet connects to the proton using Bluetooth and my garmin watch using Ant+
Using the same tablet Zwift will connect with the proton using Bluetooth but it will not connect with the garmin via ant+
Very weird as same setup worked on my old Wattbike trainer (but will older release of zwift)
Can’t be hardware related as the wattbike hub connects to both bike and watch
(As aside, Zwift wont show gears either!)
