I’ve been trying to cycle in ERG mode using the Tacx app and it seems impossible.
When I’m on the ‘Dashboard’ tab on the left hand side of the iOS app, I scroll down to the ‘Start a New Workout’ section, I then click on the green ‘Start / Power’ button, I then set the ‘Watts Setpoint’ at the bottom of the screen, when I then pedal, the wattage will not match what the set point is. For example, if I set it to 80 watts, I’m only able to do 20 watts. There is a blue ‘Start Now’ button which when I press, nothing happens, there is also a ‘WARMING UP Power Workout’ bit in the middle.
I’ve tested the Tacx App on MacOS and it’s the same behaviour as above, though different screen layout.
My trainer is a Tacx Neo 2 Smart, brand new from Garmin.
