FCM registered on iOS device BEFORE initialization

[novavision]

Please fill in the following fields:

Unity editor version: 2018.4.16f1
Firebase Unity SDK version: 6.12.0, installed using .unitypackage
Firebase plugins in use (Auth, Database, etc.): Cloud Messaging
Additional SDKs you are using (Facebook, AdMob, etc.): Facebook, AdMob
Platform you are using the Unity editor on (Mac, Windows, or Linux): Mac
Platform you are targeting (iOS, Android, and/or desktop): iOS
Scripting Runtime (Mono, and/or IL2CPP): IL2CPP

Please describe the issue here:

I am really not sure, is it an issue at all, but according to new GDPR rules we can't collect any data before user consent. I assume Firebase token use user/device ID to register a token.
I am worrying about the fact, that on iOS initial App start FCM initiates by itself and register a token. Here is a message I receive:
Firebase.FirebaseApp:InitializeAppUtilCallbacks() Firebase.FirebaseApp:CheckDependenciesAsync() Firebase.FirebaseApp:CheckAndFixDependenciesAsync() FirebaseManager:Start()
Which seems normal because my FirebaseManager checks for dependencies on Start, but doesn't trigger any Firebase class methods.

And at the end I receive this message:

If I am wrong and this doesn't violates GDPR, please close this ticket, but otherwise this problem should have investigation.

Hi @novavision

Sorry for the delay in getting back to you. You are correct that it registers for a token almost immediately, it does this based on the initialization of the library, so it can't be disabled programatically, though it can be disabled. For more information, check out: https://firebase.google.com/docs/reference/unity/class/firebase/messaging/firebase-messaging#tokenregistrationoninitenabled

[novavision]

The problem is that I have disabled "auto init enable" on both platforms but it works only on Android, on iOS it still auto initialized even setting this key in .plist

<key>FirebaseMessagingAutoInitEnabled</key>
<false/>

Why this issue closed? Please have a look on my last comment

Hi @novavision,

If your code invokes any FirebaseMessaging APIs then Messaging will enable even if you have the FirebaseMessagingAutoInitEnabled flag set to false in your .plist file. Could you double check that your application is still not invoking any methods in the Messaging API, including the configuration of listeners?

Thanks!
