When using a press or long press, the corresponding methods are called. However, they always pass the first selected element, regardless of the number of calls. for example, I select category "1", after returning to the category page, no matter which category I select, both for press and long press, category "1" will always be passed.

CategoryViewModel.cs

[ObservableProperty]

private ObservableCollection _categories = new();

[RelayCommand] async Task AddOperation(Category category) { await Shell.Current.GoToAsync(nameof(AddOperationPage), new Dictionary<string, object> { { "choosencategory", category } }); }
