AutomationProperties Name for ToolbarItem (iOS)

My toolbar item doesn't get read aloud on iOS. It just says "Taste" (button in German) when clicking it.

My code:

var toolbarItemWeiter = new ToolbarItem("Continue", "PATH_TO_MY_IMAGE", SomeAction, ToolbarItemOrder.Primary);
toolbarItemWeiter.Text = "Continue";
ToolbarItems.Add(toolbarItemWeiter);

I even tried this:

AutomationProperties.SetIsInAccessibleTree(toolbarItemWeiter, true);
AutomationProperties.SetName(toolbarItemWeiter, "Continue");

Still nothing. What am I doing wrong?
