Some apps are not configured to use Apple’s SKAdNetwork
I am getting this message from Admob. I think my Interstitial ads for IOS don’t work because of this problem. I tried to do what the documentation said I should but I wasn’t able to send the form.

I used this code to send the form but it didn’t take.

  private ConsentForm _consentForm;
    void Start()
    {
        // Set tag for under age of consent.
        // Here false means users are not under age of consent.
        DontDestroyOnLoad(this.gameObject);
        ConsentRequestParameters request = new ConsentRequestParameters
        {
            TagForUnderAgeOfConsent = false,
        };

        // Check the current consent information status.
        ConsentInformation.Update(request, OnConsentInfoUpdated);
    }

    void OnConsentInfoUpdated(FormError error)
    {
        if (error != null)
        {
            // Handle the error.
            UnityEngine.Debug.LogError(error);
            return;
        }
        // If the error is null, the consent information state was updated.
        // You are now ready to check if a form is available.
        if (ConsentInformation.IsConsentFormAvailable())
        {
            LoadForm();
        }
        // If the error is null, the consent information state was updated.
        // You are now ready to check if a form is available.
    }
    /*void LoadConsentForm()
    {
        // Loads a consent form.
        ConsentForm.Load(OnLoadConsentForm);
    }*/
    void LoadForm()
    {
        // Loads a consent form.
        ConsentForm.Load(OnLoadConsentForm);
    }
    void OnLoadConsentForm(ConsentForm consentForm, FormError error)
    {
        if (error != null)
        {
            // Handle the error.
            UnityEngine.Debug.LogError(error);
            return;
        }

        // The consent form was loaded.
        // Save the consent form for future requests.
        _consentForm = consentForm;

        // You are now ready to show the form.
        if (ConsentInformation.ConsentStatus == ConsentStatus.Required)
        {
            _consentForm.Show(OnShowForm);
        }
    }
    void OnShowForm(FormError error)
    {
        if (error != null)
        {
            // Handle the error.
            UnityEngine.Debug.LogError(error);
            return;
        }

        // Handle dismissal by reloading form.
        LoadForm();
    }
}
