Wikitude does not work. Poi do not change the position on phone position change

Question

I am trying to integrate AR poi view with Wikitude in my app. As html I used a file from the example 4_PointOfInterest_4_SelectingPois. It should render a few point around my location. It does it, but all points stay in the same position all the time, although I changed my phone position. I do not have any errors in the console. How can I fix it ?

My code:

#import "ViewController.h"
#import <WikitudeSDK/WikitudeSDK.h>
#import "PureLayout.h"

@interface ViewController () <WTArchitectViewDelegate>

@property (nonatomic, strong) WTArchitectView *architectView;
@property (nonatomic, weak) WTNavigation *architectWorldNavigation;
@property (nonatomic, weak) IBOutlet UIView *augmentedViewContainer;

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    NSError *deviceNotSupportedError = nil;
    if ( [WTArchitectView isDeviceSupportedForRequiredFeatures:WTFeature_Geo | WTFeature_2DTracking error:&deviceNotSupportedError] ) { // 1
        self.architectView = [[WTArchitectView alloc] initWithFrame:CGRectZero motionManager:nil];
        self.architectView.delegate = self;
        [self.architectView setLicenseKey:@"<LICENSE_KEY>"];

        self.architectWorldNavigation = [self.architectView loadArchitectWorldFromURL:[[NSBundle mainBundle] URLForResource:@"index" withExtension:@"html" subdirectory:@"4_PointOfInterest_4_SelectingPois"] withRequiredFeatures:WTFeature_Geo];

                                                              [self.architectView reloadArchitectWorld];

Answer 1

On some iPhone compass does not work properly, to fix it is required to reset location settings with iPhone Settings > General > Reset > Reset Location & Privacy. After that the application started to work without any code change.
