BUG: Unable to get correct values for 'attTrackingStatus', 'adTrackingEnabled' and 'advertisingId' for iOS

[stuti7]

Hello,
We are using Rudderstack packages rudder_sdk_flutter: ^3.1.0 and rudder_sdk_flutter_platform_interface: ^3.1.0 with our Flutter codebase v3.32.0.

We initialise like below:

final RudderController _client = RudderController.instance;
final builder = RudderConfigBuilder()
      ..withDataPlaneUrl('https://abc.xyz.com’,)
      ..withMobileConfig(MobileConfig(autoCollectAdvertId: true))
      ..withLogLevel(RudderLogger.VERBOSE);

_client.initialize(_writeKey, config: builder.build());

---

Firstly, while tracking for iOS devices using AppTrackingTransparency popup, on Rudderstack we see attTrackingStatus property, but it is always set to 0. Even when we choose "Allow" tracking, it shows 0.
AppTrackingTransparency.trackingAuthorizationStatus in our codebase returns correct value, but Rudderstack doesn't.
How to make attTrackingStatus accept value according to what we select?

---

Secondly, if user authorizes the app to track, we want to send advertisingId to Rudderstack. For this we are using putAdvertisingId

 final adid = await AppTrackingTransparency.getAdvertisingIdentifier();
 _client.putAdvertisingId(adid);

After adding this code, when we select "Allow tracking" from the AppTrackingTransparency popup, two new properties appear, called adTrackingEnabled: true and
advertisingId: 00AB4A5D-E0C3-4EEA-8A17-634DDB6F5662.

Now when we go to our device's app settings and disable tracking,
AppTrackingTransparency.getAdvertisingIdentifier() correctly shows 00000000-0000-0000-0000-000000000000 and
AppTrackingTransparency.trackingAuthorizationStatus correctly shows tracking denied.

But Rudderstack continues to show
adTrackingEnabled: true and
advertisingId: 00AB4A5D-E0C3-4EEA-8A17-634DDB6F5662

---

So there are 2 questions:

1. How do we set the value of attTrackingStatus in Rudderstack from our Flutter codebase?
2. How to allow adTrackingEnabled and advertisingId to correctly update their value if we have disallowed tracking?

---

Below is what we see on Rudderstack:

We are implementing it for the first time, not sure when the issue started appearing. This is an issue from iOS.

Thanks for opening this issue! We'll get back to you shortly. If it is a bug, please make sure to add steps to reproduce the issue.

Hey @stuti7,

Thanks for raising this issue.

To provide some context: the Flutter iOS SDK does not support automatic collection of the advertisingId. Users must manually set and manage this value using the putAdvertisingId API, which you’ve already implemented. Note that this value is automatically cleared when the app is closed.

Currently, we do not support setting the attTrackingStatus in Flutter iOS, nor do we provide a way to explicitly clear the advertisingId once it’s set.

I’ve raised an internal feature request to support both setting the attTrackingStatus and clearing the advertisingId in Flutter.
