Context

I need Background geolocation for android and tested this Plugin successfully for a long time. Now it seems to be broken. Remove/Add platform doesn´t help. Update Ionic Cli does not help.

Expected Behavior

Background Geolocation should update like DISTANCE PROVIDER or ACTIVITY_PROVIDER and send BackgroundGeolocation responses.

Actual Behavior

No Background Response is triggered. Not to http-post nor locally on the phone.

BUT:
When I reinstall the plugin, the location will be updates the first time. When I start the App again, there will be no more updates.
Background.geolocation.Start() dont get any errors.
chrome://inspect/ also shows no error.

Reinstall plugin ans everything works fine for 1 time.

Debug logs

First Time:

Second time:
this.m_BackgroundGeolocation.configure(this.m_Settings_Provider.getGeolocationBackgroundConfig())
.then(()=>
{
this.m_CARWAY_LocationTracker_Provider.m_BackgroundGeolocation.start()
});

No error and no update are shown
