[omatt]

Plugin Version

google_mobile_ads: ^2.0.1

Steps to Reproduce

1. Use example provided in google_mobile_ads
2. Follow this guide to display ATT dialog in iOS 15.5
3. Add requestConsentInfoUpdate() on initState() and update Info.plist with NSUserTrackingUsageDescription

@override
  void initState() {
    super.initState();

    final params = ConsentRequestParameters();
    ConsentInformation.instance.requestConsentInfoUpdate(
      params,
      () async {
        debugPrint('AAT request');
        // The consent information state was updated.
        // You are now ready to check if a form is available.
        if (await ConsentInformation.instance.isConsentFormAvailable()) {
          loadForm();
        } else{
          debugPrint('AAT Consent Form unavailable');
        }
      },
      (FormError error) {
        debugPrint('AAT error: $error');
        // Handle the error
      },
    );

    _createInterstitialAd();
    _createRewardedAd();
    _createRewardedInterstitialAd();
  }

void loadForm() {
    ConsentForm.loadConsentForm(
      (ConsentForm consentForm) async {
        var status = await ConsentInformation.instance.getConsentStatus();
        if (status == ConsentStatus.required) {
          consentForm.show(
            (FormError? formError) {
              // Handle dismissal by reloading form
              loadForm();
            },
          );
        }
      },
      (FormError formError) {
        // Handle the error
      },
    );
  }

4. Run the app

Expected results:

ATT dialog should appear

Actual results:

No ATT dialog displayed. Logs indicate that there's no consent form available

Hi @omatt, Could you provide a completed and minimal reproducible code sample so that we may verify this? In this case, it contains setup in iOS project, so it will be better if you can push the sample code into a GitHub repository and make it public.
Thank you!

[omatt]

You can use the sample provided in google_mobile_ads. Add the code snippet I've provided in the sample's main.dart and update the Info.plist in the iOS build.

[huycozy]

@omatt You can try adding testIdentifiers in ConsentDebugSettings to ConsentRequestParameters. You can get TEST-DEVICE-HASHED-ID from the console log.
For more information: https://developers.google.com/ad-manager/mobile-ads-sdk/flutter/eu-consent#testing

Sample code - only modified initState()

void initState() {
    super.initState();

    ConsentDebugSettings debugSettings = ConsentDebugSettings(
        debugGeography: DebugGeography.debugGeographyEea,
        testIdentifiers: ['TEST-DEVICE-HASHED-ID']);

    final params = ConsentRequestParameters(consentDebugSettings: debugSettings);
    ConsentInformation.instance.requestConsentInfoUpdate(
      params,
          () async {
        debugPrint('AAT request');
        // The consent information state was updated.
        // You are now ready to check if a form is available.
        if (await ConsentInformation.instance.isConsentFormAvailable()) {
          loadForm();
        } else{
          debugPrint('AAT Consent Form unavailable');
        }
      },
          (FormError error) {
        debugPrint('AAT error: $error');
        // Handle the error
      },
    );

    _createInterstitialAd();
    _createRewardedAd();
    _createRewardedInterstitialAd();
  }

Thanks @huycozy, passing a ConsentDebugSettings in ConsentRequestParameters() does show a Consent dialog, but this seems to be different from the App Tracking Transparency dialog that's mentioned in the documentation. Am I missing something?

I'm also expecting the app to appear under Tracking Settings which can be found in Settings > Privacy > Tracking

[huycozy]

@omatt I'm not sure if the dialog will change in production or different geography, can you try using another DebugGeography value to see if it achieves the expected behavior?

/cc @jjliu15 for thoughts.

With:

1. Admob account approved
2. App status in review
3. GDPR message created

In android development, following this example would result method isConsentFormAvailable() return false

Thus output 'AAT Consent Form unavailable', no dialog box appear

I/Ads     ( 6995): This request is sent from a test device.
I/flutter ( 6995): AAT request
I/flutter ( 6995): AAT Consent Form unavailable

Is there different behavior for Android and Ios platform for method isConsentFormAvailable()? I see from example above in Ios, the dialog box appear, but not in android.

Question: Is this a legitimate bug in the SDK?

Thank you

[huycozy]

Hi @c0ffeec0der
Did you add your test identifier ID into testIdentifiers? You can find it from the console log.

[c0ffeec0der]

Hi @huycozy

Sorry I haven't add it..

Just now I added and it's still not working. The response from admob is

D/UserMessagingPlatform( 5919): Stored info not exists: IDFA_freqCapNumViews D/UserMessagingPlatform( 5919): Stored info not exists: IABTCF_TCString D/UserMessagingPlatform( 5919): Stored info not exists: IABTCF_AddtlConsent W/UserMessagingPlatform( 5919): Invalid response from server.

Kindly advise, Thank you

[huycozy]

@c0ffeec0der Please check this SO answer and please provide a completed and minimal reproducible code sample so that we may verify this. Thanks!

[c0ffeec0der]

Hi @huycozy

The only difference with SO is 'tagForUnderAgeOfConsent: false' ; it's still not working..

I have created a repository with the code sample as requested

Kindly advise, Many Thanks

[huycozy]

@c0ffeec0der Yes, I also can reproduce this issue on Android whilst it works fine on iOS. I will reopen #678 due to this issue reporting for iOS. Thanks!

Without additional information, we are unfortunately not sure how to resolve this issue. We are therefore reluctantly going to close this bug for now. If you find this problem please file a new issue with the same description, what happens, logs and the output of 'flutter doctor -v'. All system setups can be slightly different so it's always better to open new issues and reference the related ones. Thanks for your contribution.
