Android location mean sea level not set

I want to access the mean sea level of an location using .NET MAUI with native Android calls:

Permissions.RequestAsync<Permissions.LocationWhenInUse>().Wait();
var locationManager = (LocationManager)MauiApplication.Current
    .GetSystemService(Context.LocationService)!;
    
var location = locationManager.GetLastKnownLocation(LocationManager.GpsProvider);
var mslLocation = location.MslAltitudeMeters;

But this results in an Java.Lang.IllegalStateException: 'The Mean Sea Level altitude of this location is not set.'.

I also tried using RequestLocationUpdates:

locationManager.RequestLocationUpdates(LocationManager.GpsProvider, 100L, 0f, new LocationListener());


class LocationListener : Java.Lang.Object, ILocationListener
{
    public void OnLocationChanged(global::Android.Locations.Location location)
    {
        var mslLocation = location.MslAltitudeMeters;
    }

    public void OnProviderDisabled(string provider)
    {

    }

    public void OnProviderEnabled(string provider)
    {

    }

    public void OnStatusChanged(string? provider, [GeneratedEnum] Availability status, Bundle? extras)
    {

    }
}

I have the following AndroidManifest.xml:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android">
    <application android:allowBackup="true" android:icon="@mipmap/appicon" android:supportsRtl="true"></application>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
</manifest>

In both cases msl location is not available. Am i missing something? Are there any permissions required? I could not find anything in the official documentation for the Location class in Java
