Marking a new resume as the "Primary" resume can be done from two locations: the Resume Tab on an Applicant’s/Talent Profile or the Resume flyout for an applicant/talent. When a new resume is available, and an existing resume is marked as "Primary," you will now see a notification stating, “New Resume Available”. Simply click on this button to select the new resume as the primary resume and it will now be available to search!
This is also going to work if you manually add in a new resume for an applicant/talent and merge the resume into the existing profile. Any time that a more recent resume has been detected, you will have the ability to click on this button to update your searches.
