[Bangle2] Issue opening app settings with Button

[espruino-discuss2]

I'm having trouble opening Settings from another app. I saw some related topics and issues, but they don't apply exactly. This issue occurs on:

• Emulator (v18.1) -> Setting visible; Stuck on "Loading..."
• Device (v19.35) -> Settings visible; "Loading" -> Settings close immideately

Here's some basic code to replicate this:

var Layout = require("Layout");
var layout = new Layout( {
  type:"txt", font:"6x8", label:"Test settings"
});
g.clear();
layout.render();

setWatch(
  function () {
    eval(require("Storage").read("myapp.settings.js"))(()=>load());
  },
  BTN,
  { edge: "rising", debounce: 50, repeat: true }
);

and the settings app, copied from the examples:

(function(back) {
  var FILE = "myapp.json";
  // Load settings
  var settings = Object.assign({
    something: 123,
  }, require('Storage').readJSON(FILE, true) || {});

  function writeSettings() {
    require('Storage').writeJSON(FILE, settings);
  }

  // Show the menu
  E.showMenu({
    "" : { "title" : "App Name" },
    "< Back" : () => back(),
    'On or off?': {
      value: !!settings.onoroff,  // !! converts undefined to false
      format: v => v?"On":"Off",
      onchange: v => {
        settings.onoroff = v;
        writeSettings();
      }
    },
    'How Many?': {
      value: 0|settings.howmany,  // 0| converts undefined to 0
      min: 0, max: 10,
      onchange: v => {
        settings.howmany = v;
        writeSettings();
      }
    },
  });
})

What's the problem? Am I missing something?
I'm pretty sure this was working on v12.

Edit:

The "Loading..." appears pretty much as soon as I release the button.

• On emulator, I can hold the button indefinitely and the menu remains

// (1) PRESS BUTTON
console.log('Open settings')
eval(require("Storage").read("vhh.settings.js"))(()=> {
   // (2) RELEASE BUTTON
   console.log('Close settings');
   load()
})

• On the device, of cource just ~2-3s.

I wouldn't be too concerned about the emulator, but try setWatch( ..... {edge:"falling"})

What's happening is you're responding on the rising edge but back responds on the falling edge, so it loads on press and then when you release it reloads.

Oh, wow. edge: "rising" was kinda staring me in the face; Didn't think to play with it.
Thank you for the quick response!

It also works fine in the emulator.
