Xamarin.Forms Switch Control is not Visible on Android prior to selecting an Entry Control

Question

I have a Registration Form which looks roughly like this

<StackLayout>
    <StackLayout 
        HorizontalOptions="FillAndExpand" 
        Padding="{x:Static local:Styles.LabelBeforeEntryPadding}">
        <Label 
            Text="{Binding LabelPasswort2}" 
            HorizontalOptions="{x:Static local:Styles.LabelHorizontalOptions}" 
            TextColor="{x:Static local:Styles.RegistrationPageTextColor}" />
    </StackLayout>
    <custom:StrypeEntry 
        Text="{Binding Passwort2}" 
        IsPassword="true" 
        IsEnabled="{Binding ControlsEnabled}" 
        HorizontalOptions="FillAndExpand" />
</StackLayout>
<!--Newsletter-->
<StackLayout 
    Orientation="Horizontal" 
    HorizontalOptions="StartAndExpand">
    <Switch 
        IsToggled="{Binding Newsletter}" 
        IsEnabled="{Binding ControlsEnabled}" 
        VerticalOptions="StartAndExpand" 
        HorizontalOptions="StartAndExpand"  />
    <Label 
        Text="{Binding LabelNewsletter}" 
        VerticalOptions="CenterAndExpand" 
        HorizontalOptions="Start" 
        TextColor="{x:Static local:Styles.RegistrationPageTextColor}" />
</StackLayout>
<!--Datenschutz-->
<StackLayout 
    Orientation="Horizontal" 
    HorizontalOptions="StartAndExpand">
    <custom:StrypeSwitch 
        IsToggled="{Binding Privacy}" 
        IsEnabled="{Binding ControlsEnabled}" 
        VerticalOptions="StartAndExpand" 
        HorizontalOptions="StartAndExpand" />
    <Label 
        Text="{Binding LabelPrivacy}" 
        VerticalOptions="CenterAndExpand" 
        HorizontalOptions="Start" 
        WidthRequest="300" TextColor="{x:Static local:Styles.RegistrationPageTextColor}" />
</StackLayout>

The Problem is that the Switches are not visible when displaying the Form, they only become visible when an entry is focused.

The StrypeEntry is just a customized Entry with Border Corder and a prop for Capitalize, nothing fancy and for the switch I made a Custom Renderer to fix the issue of not displaying.

I already tried the fix for the ButtonText Alignment which did not help (Xamarin.Forms: wrong button text alignment after click (Android))

I also tried this

public override void ChildDrawableStateChanged(View child)
{
    base.ChildDrawableStateChanged(child);

    Control.Text = Control.Text;
    Control.Checked = Control.Checked;
}

but still no fix

(I'm testing on a GT-I9505 with Android 4.4.2. The Version of the Xamarin.Forms Assemblies is 1.2.2.0)

Please help me, Thank you

Seems like I have to answer my own question.

I fixed the issue by adding a Height- and WidthRequest to the Switch in the xaml

Hope this helps someone else. And maybe if you find a better solution, please let me know.
