I added in my profile the specialty field needed to answer a GBK question but I still can't answer it. Why?

Users who adds a new "specialty" field of expertise to their profiles will not be provided access to GBK filtered by this particular field for 72 hours after implementing this change. This aims to preventing users from modifying their profiles in order to "follow" the specialties requested in the questions. 

This restriction will not apply to profiles created less than a month ago.
