Apparently there is no way for you to completely disable Answers
, based on in this discussion in the Twitter community.
Note that as mentioned by the staff member, Fabric now has two separate install modes: one for Crashlytics and one for Answers . You can try to make a new installation for the same application and only enable Crashlytics .
Otherwise, as at the conclusion of this discussion above, the "bundle id / package name" was requested for the user and then it looks like it was manually deleted by a team member.
