Xamarin Forms TapGestureRecognizer not working iOS

I have been facing an issue many have been in the past but none of the solutions seem to work.

I have a Grid with in it a StackLayout with TapGesture.

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:local="clr-namespace:WodTracker.App.Components"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="WodTracker.App.Pages.Account.PinCodePage"
             BackgroundColor="White">
    <ContentPage.Content>
        <StackLayout VerticalOptions="FillAndExpand" BackgroundColor="White">
            <StackLayout.GestureRecognizers>
                <TapGestureRecognizer NumberOfTapsRequired="1" Tapped="NumberCommand" CommandParameter="1"/>
            </StackLayout.GestureRecognizers>
            <Label HorizontalOptions="Center" VerticalOptions="EndAndExpand"  Text="1"  FontSize="Title" FontAttributes="Bold" TextColor="Black"></Label>
            <Label HorizontalOptions="Center" VerticalOptions="EndAndExpand" Text=" " FontSize="Small" TextColor="Black"></Label>
        </StackLayout>
    </ContentPage.Content>
</ContentPage>

The code that should be hit is as followed. No initializing in the constructor just method.

private async void NumberCommand(object sender, EventArgs e) 
{
     var button = sender;
}

On Android the Tapped Command "NumberCommand" is executed. But on iOS it does not fire. On this website I have found people mentioning

InputTransparent="True"

I have tried adding this to the Parent Grid and the StackLayout without any success.

Hope someone can help.

I am using Visual Studio 2022 and Xamarin Forms 5.0.0.2244

Solved

It was an issue with 'InputTransparent="True"', after rebuilding the page step by step based on comments from ToolmakerSteve I was able to fix it. Thanks for all the help.

Code

<StackLayout VerticalOptions="FillAndExpand" BackgroundColor="White">
                <StackLayout.GestureRecognizers>
                    <TapGestureRecognizer NumberOfTapsRequired="1" Tapped="NumberCommand" CommandParameter="1"/>
                </StackLayout.GestureRecognizers>
                <Label HorizontalOptions="Center" VerticalOptions="EndAndExpand"  Text="1"  FontSize="Title" FontAttributes="Bold" TextColor="Black"></Label>
                <Label HorizontalOptions="Center" VerticalOptions="EndAndExpand" Text=" " FontSize="Small" TextColor="Black"></Label>
</StackLayout>

Code behind

private async void NumberCommand(object sender, EventArgs e)
{
    var button1 = (TapGestureRecognizer)sender;
    string commandParameter = button1.CommandParameter.ToString();
}
