How to stop the default locationmanager and use arview.injectlocation (IOS10)?
my guess is, that you set the UseInjectedLocation property of the ArchitectView untimely, preventing it from being actually set. This property can only be set after you have called the LoadArchitectWorldFromURL function and have supplied it with the Wikitude.Architect.WTFeatures.Geo flag due to internal restrictions.
I suspect this is not the case for your project, which would result in UseInjectedLocation always being set to its default value, which is false.
Please check whether this is the case for your project and get back to me.
