In the Google Deletion API documentation, APP_INSTANCE_ID is now marked as "Deprecated".
In the documentation it is mentioned that the the APP_INSTANCE_ID is only supported if the firebaseProjectId is set which is deprecated in favor of the propertyId field. Are these fields now equivalent?
Also, if it is deprecated it would be best not to use it anymore, but to use the alternative provided. In this case, what should I use? Another user id type is USER_ID" field, but this redirects to Google Analytics User ID. Is this the same as Firebase User ID? Can the request be done with Firebase User ID?
Should I should have asked this here to point out the accepted answer might not be the best anymore? How do I delete user analytics data from Firebase using userDeletionRequests:upsert?
