"Missing Push Notification Entitlement" warning after adding Crashlytics SDK

[oct-test]

Unity editor version: 2019.3.0f3
Firebase Unity SDK version: 6.13
Firebase plugins in use (Auth, Database, etc.): Crashlytics
Additional SDKs you are using (Facebook, AdMob, etc.): Facebook Analytics, Appsflyer
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

Issue:
I received a warning email from Apple for recent App Store submission saying "ITMS-90078: Missing Push Notification Entitlement - Your app appears to register with the Apple Push Notification service, but the app signature's entitlements do not include the "aps-environment" entitlement.". My game is not using the push notification service.

Before adding the Firebase Crashlytics SDK, there was no such warning email from Apple. Hence, I am suspecting that this warning email arrived due to Firebase SDK.

Have you been able to reproduce this issue with just the Firebase Unity quickstarts (this GitHub project)?
No, I can't do that as to this bug I have to submit a build to App Store.

What's the issue repro rate?
100%

This issue does not seem to follow the issue template. Make sure you provide all the required information.

AFAIK, Crashlytics does not require Push Notification either. Are you sure you did not switch Push Notifications to On in your Xcode project?
If this is off, even any SDK wants to receive push notification, none can receive it.

Also, aps-environment seems only used for macOS. And Crashlytics does not support macOS.

Thank you for the response @chkuang-g. I did check my Xcode project settings and I haven't enabled push notifications.

I understand that the game won't receive any push notifications but I wanted to get rid of that annoying warning email from Apple. Are there any other settings I could check to help you figure out the problem?

[chkuang-g]

Not as I aware of. Apple should only determine either your app is using push notification based on your Xcode project configuration.

I think you should consult with Apple and see why this email occurred.

Thank you @chkuang-g. Let me check with Apple on this issue. I will let you know the information I will receive from them.
