ios – Fundamental thread blocking loading of admob rewarded advert

Each time I’m calling loadAd() perform both from onAppear() or with a button click on, it is giving the error:

Fundamental thread blocked by synchronous property question on not-yet-loaded property (assetProperty_Tracks) for HTTP(S) asset. This might have been an issue if this asset had been being learn from a gradual community.

Leading to giving me “Advert wasn’t loaded”. Right here is my loadAd():

class AdCoordinator: NSObject, GADFullScreenContentDelegate, ObservableObject {
  personal var advert: GADRewardedAd?

  func loadAd() {
    GADRewardedAd.load(
      withAdUnitID: "ca-app-pub-3940256099942544/1712485313", request: GADRequest()
    ) { advert, error in
      if let error = error {
        return print("Did not load advert with error: (error.localizedDescription)")
      }

      self.advert = advert
        self.advert?.fullScreenContentDelegate = self
    }
  }

  func presentAd(from viewController: UIViewController) {
    guard let fullScreenAd = advert else {
      return print("Advert wasn't prepared")
    }

      fullScreenAd.current(fromRootViewController: viewController, userDidEarnRewardHandler: didEarnedReward) // didEarnedReward prints "reward earned"
  }
}

The advert unit ID right here is from Google’s documentation.
