SfDataGrid group summary not updating

I have problems with updating group summary for my DataGrid - when I edit a cell (OrderID in this case) it's not updating group summary. To simplify the problem I used the OrderInfo model from your docs - https://help.syncfusion.com/xamarin/sfdatagrid/getting-started#create-datamodel-for-the-sfdatagrid with added INotifyPropertyChanged. Here is my DataGrid setup:

            OrderInfoRepository viewModel = new OrderInfoRepository();
            dataGrid.ItemsSource = viewModel.OrderInfoCollection;
            dataGrid.GroupColumnDescriptions.Add(new GroupColumnDescription() { ColumnName = "ShipCountry" });
            dataGrid.AllowEditing = true;

            GridSummaryRow summaryRow = new GridSummaryRow
                ShowSummaryInRow = true,
                Title = "{Key}: {Total}"
            summaryRow.SummaryColumns.Add(new GridSummaryColumn()
                Name = "Total",
                MappingName = "OrderID",
                Format = "{Sum}",
                SummaryType = SummaryType.DoubleAggregate
            dataGrid.CaptionSummaryRow = summaryRow;

            dataGrid.GridViewCreated += (object sender, GridViewCreatedEventArgs e) =>
                dataGrid.View.LiveDataUpdateMode = LiveDataUpdateMode.AllowSummaryUpdate;

Did I missed something?
