Deferred deeplink not working in appstore version of the app

[NikAshanin]

Hello!

I have a production app in appstore (iOS). Actually, I integrated deferred deeplink into it for transfering user_id parameter from the link after installation via appstore. So, after pressing the link appstore opens and I can install the app, but when I open the app there is no deferred deep link callback and I cant receive user id from the initial link.

The initial link itself is like https://MYDOMAIN.go.link?adj_t=ADJUST_TOKEN&adj_deep_link_id=AUTOGENERATED_DEEP_LINK_ID&user_id=USER_ID

The code itself looks like:

final adjustConfig = AdjustConfig('ADJUST_TOKEN_FROM_CONSOLE', AdjustEnvironment.production)..logLevel = AdjustLogLevel.verbose;
final deviceID = await getDeviceId();
if (deviceID != null) {
  adjustConfig.externalDeviceId = deviceID;
}
adjustConfig
  ..isCostDataInAttributionEnabled = true
  ..isSendingInBackgroundEnabled = true
  ..isLinkMeEnabled = true
  ..isIdfvReadingEnabled = true
  ..isSkanAttributionEnabled = true
  ..isDeferredDeeplinkOpeningEnabled = false
  ..deferredDeeplinkCallback = (deeplink) {
    debugPrint('✅ Adjust: Callback deferredDeeplinkCallback called: $deeplink');
    if (deeplink != null && deeplink.isNotEmpty) {
      unawaited(SOME LOGS HERE);
    }
    try {
      unawaited(_handleAdjustDeferredDeeplink(deeplink));
    } catch (e, stackTrace) {
      log('❌ Adjust: Error in deferredDeeplinkCallback: $e');
      log('Stack trace: $stackTrace');
    }
  }
  ..attributionCallback = (attribution) {
    try {
      _handleAdjustAttribution(attribution);
    } catch (e, stackTrace) {
      log('❌ Adjust: Error in attributionCallback: $e');
      log('Stack trace: $stackTrace');
    }
  };

try {
  Adjust.initSdk(adjustConfig);
  log('✅ Adjust SDK initialized successfully');
} catch (initError, initStackTrace) {
  log('❌ Adjust: Error in initSdk: $initError');
  log('Stack trace: $initStackTrace');
  return;
}

The code above written in main.dart before runapp function.

We have probablistic method enabled in adjust console as well. And also, common deeplink if app installed already works fine, but not the deferred one. All other functions from Adjust works fine as well.

Adjust Flutter SDK version: adjust_sdk 5.4.4

So, deferredDeeplinkCallback is not working on a production app. It is not called at all. Could you please kindly help with that issue?

Hey @NikAshanin,

Are you uninstalling the app and forgetting it from your app's testing console before running the test?

[NikAshanin]

Hey @uerceg ,

Yes, I have tried it on my device. We have also tried it on multiple "clear" devices because it is production appstore version of the app.

Thanks for the confirmation. In theory, if the device is unknown to us, it should work. This should be checked by our team to see what's up with the link you're using and whether there's something wrong in the setup. Can you please ping the support@adjust.com (or a dedicated account manager if you have one) and link this issue and this will be checked?

Yep, I have wrote support and provide all the details. Just waiting for a new reply for 2 days already. Seems need to wait a bit more, thx.
