I maintaining .NET MAUI application that are created using .NET MAUI Blazor hybrid application project. now wwe need to publish it on Apple Appstore and there also some platform specific codes for android as well. so what i did is create .NET MAUI multi project and configured projects seperately. then i published windows version and android version and ios versions. when debugging ios application there is no problem in simulator. but after publishing that project to appstore I getting rejected because app is crashing when launching in iPad Air

here is my code in csproj file

<Project Sdk="Microsoft.NET.Sdk.Razor">

	<PropertyGroup>
		<TargetFramework>net8.0-ios</TargetFramework>
		<SupportedOSPlatformVersion>11.0</SupportedOSPlatformVersion>
		<OutputType>Exe</OutputType>
		<Nullable>enable</Nullable>
		<ImplicitUsings>enable</ImplicitUsings>
		<UseMaui>true</UseMaui>
		<EnableDefaultContentItems>false</EnableDefaultContentItems>
	</PropertyGroup>

	<PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Debug|AnyCPU'">
	  <BuildIpa>False</BuildIpa>
	</PropertyGroup>

    the error is just an uncaught exception. that is your code throw an exception. may be related to layout on an iPad. your code is failing on a iPad Air 5th Gen (Wi-Fi) - OS 17.6
