### [REQUIRED] Please describe the question here:
When uploading the AppBundle that uses FCM to Google Play Console, the following warning was displayed:

'The developer of androidx.fragment:fragment (androidx.fragment:fragment) has reported version 1.0.0 as outdated. Consider upgrading to one of the following versions before publishing a new release: 1.1.0+.'

After contacting Firebase Support, they responded that the latest varsion (currently 1.6.0) is available, so we are considering taking action to add this to the mainTemplate.gradle of the Unity project.

Regarding the warning about the androidx.fragment version, do you have any plans to address this in Firebase SDK, and if so, when can it be expected to be provided?

Start by reproducing the Google Play Console warning with the listed Unity 2020.3.38f1, Firebase Unity SDK 11.3.0, FirebaseMessaging.unitypackage, and Android AppBundle setup. Inspect the project's mainTemplate.gradle and determine how the androidx.fragment version is supplied; done means establishing whether the Firebase SDK can provide the newer version without breaking the build.
