Repro for the TableSection problem.

On iOS 11, TableSection with no Title <TableSection/> is rendered as an empty row.

And on iOS 10.3 (and previous versions), the same TableSection is not rendered (no row generated). It is the expected behavior.

The "bug" is still there with the 2.5.0-pre2.

I attached a repro and the version infos.

I have found a workaround with a custom renderer:

    public class ExtendedTableViewRenderer : TableViewRenderer
        protected override void OnElementChanged(ElementChangedEventArgs<TableView> e)

            if (this.Control != null && e.NewElement != null)
                this.Control.EstimatedSectionHeaderHeight = 0;

In your TableViewModelRenderer.GetHeightForRow method, you should return 0 for TableSection with no Title instead of UITableView.AutomaticDimension, at least since iOS 11.
