Ive just got apple tv after using android for zwift for many years.
On ATV I cant figure out how to make a manual turn at a junction. On android when the junction icon appears i flick up on the screen which then shows the other road options for me to select.
If using the Apple Remote when the turn appears on screen press the trackpad and you can then scroll left/right and choose the option you’d like. It can be frustrating though, so often I instinctively swiped up first which brings up the main option menu.
