Xamarin.Forms.Maps 2.3.4 custom MapRenderer disables everything : <p>My problem occurs after I updated Xamarin.Forms and Xamarin.Forms.Maps to the new version (2.3.4).</p>

<p>After that I also updated all google play services in Android project (and a lot of libraries that I hate).</p>

<p>The main problem is that I have a custom MapRenderer for custom pins, in iOS and UWP works fine, but in Android version this custom MapRenderer brokes all the Map. Any property change or method call seems to be ignored.</p>

<p>For example I have a button to toggle the map type (Hybrid or Street) and that action never changes it. I also noticed (according this tutorial: <a href="https://developer.xamarin.com/guides/xamarin-forms/application-fundamentals/custom-renderer/map/customized-pin/" rel="noreferrer">https://developer.xamarin.com/guides/xamarin-forms/application-fundamentals/custom-renderer/map/customized-pin/</a>) that the property "VisibleRegion" never changes so the following code never executes:</p>

<pre><code>protected override void OnElementPropertyChanged(object sender, PropertyChangedEventArgs e)
    {
        base.OnElementPropertyChanged(sender, e);

        if (e.PropertyName.Equals("VisibleRegion") &amp;&amp; !_isDrawn)
        {
            // Do something with your custom map
        }
    }
</code></pre>

<p>Inside that <code>if</code> i used to populate my custom pins (like the tutorial above) and now my Map is always empty.</p>

<p>Now i populate my map inside the <code>IOnMapReadyCallback</code> and it works fine, but the I still have the bindings problem.</p>

<p>If I ignore the custom MapRendered (removing the assembly line) all the bindings starts working fine but my map now have the old pins and all customization is gone (obviously).</p>

<p>In the PCL I have things like <code>MyMap.MoveToRegion(...)</code> and <code>MyMap.MapType = _currentType;</code> but those instructions only works if a don't use a custom MapRenderer.</p>

<p>My custom MapRenderer is almost the same as the tutorial above.</p>

<p>The custom Map is created with C# and not with XAML, it doesn't have any XAML binding but any property change or method call like the MoveToRegion or MapType is totally ignored if i'm using the MapRenderer.</p>

<p>Any help?</p>

<p>Thanks</p>
