Any ideas here. It’s worked fine for a couple of years and it’s just gone. Nothing there. Game Sound Volume, 3D world volume, powers estimation mode, Power Display etc all there. But not the slider for Trainer Difficulty. Did it move?
check if you paired the trainer as controllable.
I have the same issue - how do you verify?
Open the pairing screen and see if controllable is selected.
I’m having the same issue on android. Controllable trainer is definitely selected
Answer was on logging in make sure the right hand button (power controlled trainer or something) is clicked, as well as the top one - they both need to be connected (as well as your Heart Rate or Cadence sensor) connected.
