Hi,
I can run my watchface in the simulator - but I'm not able to click on a button (using the mouse in the simulator).
Also under "Simulation" I found nothing which allows me to simiulate (trigger) Backlight.
I use Simulator Version 4.0.3 and Fenix 6s as well as Fenix 5x as target.
The watch face shows corretly - I only found no way to trigger the buttons.
