Elements not responding to taps inside TabView (App broker error)

[felipe pedroti raymundo]

I have this layout on my application:

<?xml version="1.0" encoding="utf-8" ?>

<ContentPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" xmlns:tabView="clr-namespace:Syncfusion.XForms.TabView;assembly=Syncfusion.SfTabView.XForms" xmlns:opcoestarefasview="clr-namespace:TaskFly.Views.OpcoesTarefasView" x:Class="TaskFly.Views.OpcoesTarefasGuiaView" Title="Tarefas">

    <ContentPage.ToolbarItems>

        <ToolbarItem x:Name="cmd_tarefa" Icon="ic_tarefa.png" Activated="Cmd_tarefa_Activated" />

    </ContentPage.ToolbarItems>

    <ContentPage.Content>

        <StackLayout BackgroundColor="White" VerticalOptions="FillAndExpand">

            <tabView:SfTabView VisibleHeaderCount="4" SelectionChanged="SfTabView_SelectionChanged" VerticalOptions="FillAndExpand" x:Name="TabView" TabHeaderPosition="Bottom" DisplayMode="ImageWithText" EnableSwiping="False">

                <tabView:SfTabView.OverflowButtonSettings>

                    <tabView:OverflowButtonSettings DisplayMode="ImageWithText" Title="Mais" TitleFontColor="#0097C5" />

                </tabView:SfTabView.OverflowButtonSettings>

                <tabView:SfTabView.SelectionIndicatorSettings>

                    <tabView:SelectionIndicatorSettings Position="Top" />

                </tabView:SfTabView.SelectionIndicatorSettings>                

                <tabView:SfTabItem Title="Coment." x:Name="tabComentario" TitleFontColor="#0097C5">

                    <tabView:SfTabItem.Content>

                        <opcoestarefasview:ComentariosView x:Name="vwComentario" />

                    </tabView:SfTabItem.Content>

                </tabView:SfTabItem>

            </tabView:SfTabView>

        </StackLayout>

    </ContentPage.Content>

</ContentPage>

And this is my ContentView

<?xml version="1.0" encoding="utf-8" ?>

<ContentView xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" x:Class="TaskFly.Views.OpcoesTarefasView.ComentariosView" xmlns:syncfusion="clr-namespace:Syncfusion.ListView.XForms;assembly=Syncfusion.SfListView.XForms" xmlns:controls1="clr-namespace:ImageCircle.Forms.Plugin.Abstractions;assembly=ImageCircle.Forms.Plugin" xmlns:shimmer="clr-namespace:Syncfusion.XForms.Shimmer;assembly=Syncfusion.Core.XForms" BackgroundColor="White">

    <ContentView.Content>

        <shimmer:SfShimmer x:Name="shimmer" VerticalOptions="FillAndExpand" Type="Feed">

            <shimmer:SfShimmer.Content>

                <StackLayout>

                    <syncfusion:SfListView x:Name="listaComentario" AutoFitMode="DynamicHeight" Margin="10">

                        <syncfusion:SfListView.ItemTemplate>

                            <DataTemplate>

                                <ViewCell>

                                    <StackLayout Orientation="Horizontal">

                                        <StackLayout Orientation="Vertical">

                                            <Label Text="{Binding DataDescricao, StringFormat='Feito {0}'} " TextColor="Black" FontSize="12" />

                                            <Label Text="{Binding FaseTarefa.Descricao, StringFormat='Fase: {0}'}" TextColor="Black" FontSize="12" />

                                            <Label x:Name="lblComentario" Text="{Binding Descricao}" TextColor="Black" FontSize="16" Margin="0,5,0,0">

                                                <Label.GestureRecognizers>

                                                    <TapGestureRecognizer  Tapped="CallButton" NumberOfTapsRequired="1" CommandParameter="{Binding Descricao}" />

                                                </Label.GestureRecognizers>

                                </ViewCell>

                            </DataTemplate>

                        </syncfusion:SfListView.ItemTemplate>

                    </syncfusion:SfListView>

                    <Grid Margin="20,10">

                        <Picker x:Name="PickerSelecionarUsuario" Title="Selecionar Usuario" Grid.Column="1" Grid.Row="1" SelectedIndexChanged="PickerSelecionaUsuario_SelectedIndexChanged" ItemDisplayBinding="{Binding UsuarioNomeSetor}" />

                    </Grid>

                    <Label Text="Comentário" Margin="20,10" />

                    <Editor x:Name="Comentario" VerticalOptions="Center" Margin="20,0,20,8" AutoSize="TextChanges" />

                    <Button x:Name="cmd_fase" WidthRequest="153" HeightRequest="40" BackgroundColor="#0097C5" Text="Confirmar" FontSize="14" TextColor="White" HorizontalOptions="Center" VerticalOptions="End" Margin="0,0,0,10" Clicked="Cmd_fase_Clicked" />

                </StackLayout>

            </shimmer:SfShimmer.Content>

        </shimmer:SfShimmer>

    </ContentView.Content>

</ContentView>

If I tap on a list item, it responds normally, but when I tap in the Editor or the Pickers control, I'm getting this kind of log from device, and keyboard are not showing:

Error (52) / SpringBoard(KeyboardArbiter): [<_UIKeyboardArbiterHandle: 0x281e861c0; PID 138: (null) <(null)>; hosting PIDs {(

When the view is outside tabview, works normally

Updating: the issue only occurs in iOS, on android it works fine
