Android: Changes to textbox from codebehind are not reflected to viewmodel

[DrHardReset]

In my application RoMi I am setting the Text property of a TextBox in the code behind class.
In the windows build this change is correctly reflected to the corresponding viewmodel.
The android build behaves different and does not reflect the change to the viewmodel.

Is this a bug or am I missing something?

View:

<TextBox x:Name="PdfUrl"
	 PlaceholderText="Enter MIDI PDF URL"
	 Text="{Binding DownloadPdfUrl, Mode=TwoWay}"/>

View codebehind:

private void CobDeviceSelection_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    if (e.AddedItems.Count == 0)
    {
        return;
    }

    PdfUrl.Text = ((KeyValuePair<string, string>)e.AddedItems[0]).Value;
}

Viewmodel:

[ObservableProperty]
private string downloadPdfUrl = string.Empty;
