After sending using [RelayCommand] in maui the setter in ViewModel receives truncated string in Maui - string

Question

After sending using [RelayCommand] in maui the setter in ViewModel receives truncated string in Maui.
Example orginal string: "https://twit.memberfulcontent.com/rss/9039?auth=m9FZurRandomAuthonumbers6yB"
The value of URL is good here:
[RelayCommand]
async Task Tap(string Url)
{
System.Diagnostics.Debug.WriteLine("Tap Sending: " + Url);
await Shell.Current.GoToAsync($"{nameof(ShowPage)}?Url={Url}");
}
when recieving here URL is truncated:
namespace NerdNewsNavigator2.ViewModel;
[QueryProperty("Url", "Url")]
public partial class ShowViewModel : ObservableObject
{
#region Properties
readonly TwitService _twitService;
public ObservableCollection<Show> Shows { get; set; } = new();
public string Url
{
set
{ // value is truncated string from Tap above.
System.Diagnostics.Debug.WriteLine("ShowViewModel Recieving url: " + value);
_ = GetShows(value);
OnPropertyChanged(nameof(Shows));
}
}
// Code shortened for brevity
Example of passed string:
"https://twit.memberfulcontent.com/rss/9039"
It gets truncated at ?Auth
Any suggestions on what I may be doing wrong? Or suggestion on a better way to do this? It works fine for string that do not have a ? mark in them. One hundred percent working except on this specific type of string.
I was expecting the string not to be truncated.

Correct way to pass data between pages in MAUI:
When you navigate:
Dictionary<string, object> query = new()
{
{ nameof(MyModel), myModel }
};
await Shell.Current.GoToAsync($"{nameof(MyPage)}", query);
When you are navigated:
public void ApplyQueryAttributes(IDictionary < string , object > query)
{
myModel = query[nameof(MyModel)] as MyModel;
}
(This solves more than the problem with sanitization)
