app behaves differently in IDE vs bare metal

I'm having infinitely more issues designing this simple app than I thought I would have. Since I'm using the quick launch (app? widget? witchcraft?) I wanted to be able to swipe down & just turn off the screen (to avoid it accidentally swiping on the cuff on my jacket). So I programmed what is (probably) the simplest Bangle app that has been made:

Bangle.setBacklight (false);
Bangle.showClock();

This works perfectly as intended on the web IDE, however when I loaded into my BangleJS2, the screen turns off fine, but then it displays a loading screen, and needs to be hard-rebooted to regain control. Does anyone know how to prevent this? Or if my approach is just completely off?

you may add
Bangle.setOptions({btnLoadTimeout: 0})
so that the button press will not call the clock, but yes, you need some reading :)

sorry, I read it a bit fast, ignore me :)

Hi! I think the issue is just that while your app is being loaded it's immediately trying to load into another app - and when that happens, the second load request ends up getting ignored so then the Bangle's just running an empty app that's not even updated the screen.

Instead, you could try loading after a small delay:

Bangle.setBacklight (false);
setTimeout(() => Bangle.showClock(), 50);

and that might do it for you?
