DontDestroyOnLoad Error with Firebase Analytics

Hi. I am trying to export a build to Android, but I get the following error:

 Error building Player: InvalidOperationException: The following game object is invoking the DontDestroyOnLoad method: Firebase Services. Notice that DontDestroyOnLoad can only be used in play mode and, as such, cannot be part of an editor script.

I am using Firebase Analytics. I have tried cleaning the project of anything related to Firebase and reimported the newest version, but with no luck. Any ideas?
