Hi Christopher
Unfortunately the nested <smart-menu-item><span>{{ userName | async }}</span></smart-menu-item> works only for static content like:
<smart-menu-item><span>SOMEBODY</span></smart-menu-item> and not for async angular items.
The userName is specified in angular controller: public userName: Observable<string>;
The displayed menu item for async variable is like “Item 3” instead of variable value.
