I have a live app on AppStore that uses Facebook Audience Network (FAN) for showing ads. The live version uses FAN SDK v 4.26.0 and successfully shows native and interstitial ads. However the latest development version of the app uses FAN SDK v 4.99.1. The same Ad Placement IDs are used for interstitial and native ads. Even though the app is getting the ads but gets crashed after some time raising exception that the ad is not valid.
Uncaught exception: Native ad <FBNativeAd: 0x180a7d60> passed to <FBAdGenericHeight300View: 0x180c9360;
frame = (0 0; 0 0); layer = <CALayer: 0x182916b0>>, but the native ad is not valid.
Here is the Crash Log:

I am using the latest sample code mentioned on the official Facebook developer site.
#import <FBAudienceNetwork/FBAudienceNetwork.h>
@interface SearchViewController () <FBNativeAdDelegate>
@property (strong, nonatomic) FBNativeAd *nativeAd;
@property (strong, nonatomic) FBNativeAdView *fbNativeAdView;
@end
@implementation SearchViewController
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
FBNativeAd *nativeAd = [[FBNativeAd alloc] initWithPlacementID:@"2222222222222222_2222222222222222"];
nativeAd.delegate = self;
[nativeAd loadAd];
}
- (void)nativeAdDidLoad:(FBNativeAd *)nativeAd
{
self.nativeAd = nativeAd;
if (self.nativeAd && self.nativeAd.isAdValid) {
FBNativeAdView *adView;
adView = [FBNativeAdView nativeAdViewWithNativeAd:self.nativeAd
withType:FBNativeAdViewTypeGenericHeight300];
if (self.fbNativeAdView && self.fbNativeAdView.superview) {
[self.fbNativeAdView removeFromSuperview];
}
self.fbNativeAdView = adView;
if (self.fbNativeAdView) {
[self adjustNativeAdPlacement];
}
[self.collectionView addSubview:adView];
}
}
- (void)nativeAd:(FBNativeAd *)nativeAd didFailWithError:(NSError *)error
{
NSLog(@"Ad failed to load with error: %@", error);
}
@end
Please anyone help me in figuring out the issue?
