getLocationAuthorizationStatus not working on android 13 with ionic cordova production builds about cordova-diagnostic-plugin HOT 1 CLOSED

This plugin is used in multiple production apps that use background location on both Android & iOS so sounds like a problem with your project/development environment, not this plugin.
The plugin code itself will not behave differently in debug vs release builds.

1. The ionic plugin doesn't have the diagnostic.permission.ACCESS_BACKGROUND_LOCATION

https://github.com/dpa99c/cordova-diagnostic-plugin/blob/master/www/android/diagnostic.js#L32

2. The ionic plugin missing features/methods

The plugin does not lack the features required to request background location permission on Android 13+ - this is supported and being used in production.

Note that to request background location permission on Android 13+, you must first request and be granted foreground location permission before requesting background location permission:

cordova.plugins.diagnostic.requestLocationAuthorization(function(status){
	if(status === cordova.plugins.diagnostic.permissionStatus.GRANTED){
		cordova.plugins.diagnostic.requestLocationAuthorization(function(status){
		   console.log("Background location permission granted");
		}, onError, cordova.plugins.diagnostic.locationAuthorizationMode.ALWAYS, cordova.plugins.diagnostic.locationAccuracyAuthorization.FULL);
	}
}, onError, cordova.plugins.diagnostic.locationAuthorizationMode.WHEN_IN_USE, cordova.plugins.diagnostic.locationAccuracyAuthorization.FULL);

You must also include ACCESS_BACKGROUND_LOCATION permission in your AndroidManifest.xml as well as ACCESS_FINE_LOCATION/ACCESS_COARSE_LOCATION.

Please refer to the example project for reference and to validate the plugin works correctly.

Note this is a Cordova plugin: the Ionic Typescript wrapper for this plugin is not part of the plugin code and is independently maintained.
