Current Behavior

If multiple parallel calls to Geolocation.getCurrentPosition() are made, only last one returns any result, success or error.

Expected Behavior

Every call to Geolocation.getCurrentPosition() should have it's promise fullfilled or rejected.
This shoud be the way, besides what the plugin does internally (which native API uses, cached position, ...)

Sample Code or Sample Application Repo

const params = {
    enableHighAccuracy: true,
    maximumAge: 20000,
    timeout: 50,
};

console.log('position 1 start')
Capacitor.Plugins.Geolocation.getCurrentPosition(params).then(
  position => console.log('position 1', position), 
  error => console.error('position 1 error', error)
);
console.log('position 2 start')
Capacitor.Plugins.Geolocation.getCurrentPosition(params).then(
  position => console.log('position 2', position), 
  error => console.error('position 2 error', error)
);
console.log('position 3 start')
Capacitor.Plugins.Geolocation.getCurrentPosition(params).then(
  position => console.log('position 3', position), 
  error => console.error('position 3 error', error)
);
console.log('position 4 start')
Capacitor.Plugins.Geolocation.getCurrentPosition(params).then(
  position => console.log('position 4', position), 
  error => console.error('position 4 error', error)
);

Reproduction Steps

• Create a new test project based on capacitor starter npx @capacitor/cli create
• Add the example code below to any JS file/script (I put it in js/capacitor-welcome.js file)

Having the same issue

[AE1NS]

Same here. No news on this?

Edit:
A workaround could be a helper method, that returns a custom observable, that is resolved for all subscribers, when 'Plugins.Geolocation.getCurrentPosition' returns a value:

private _getCurrentPosition$: Subject<LatLng>;

...

getCurrentPosition() {
    if (!this._getCurrentPosition$) {
        this._getCurrentPosition$ = new Subject();
        Plugins.Geolocation.getCurrentPosition().then((currentPosition) => {
            this._getCurrentPosition$.next(currentPosition);
            this._getCurrentPosition$.complete();
            this._getCurrentPosition$ = null;
        });
    }

    return this._getCurrentPosition$;
}

I've noticed getCurrentPosition doesn't resolve at all if watchPosition() has been called before, not sure if related
