What might cause an icon not to display? If I create a blank Xamarin Forms app and use the example from the documentation I can get an icon to display but in three other active projects with lots of code any call to NavigationPage.SetTitleIcon is ignored - no errors, just no icon. NavigationPage.SetBackButtonTitle works in every case.
- Is there something specific about the size of the icon/image that must be used?
- Does it require a specific file extension? JPG is used in the example and but isn't working for me.
- I've tried using ContentPages, NavigationPages, ContentPages within NavigationPages, TabbedPages ...
Any ideas would be appreciated.
thanks.
