Tick Sales Navigator or Recruiter on that sender Details tab when the LinkedIn account has that product. The matching import cards unlock after the sender is Active.
Tick the product on Details
The checkboxes do not buy Sales Navigator or Recruiter. They tell ReachyReach that this LinkedIn account already has the product.
Connect a LinkedIn sender and wait until status is Active.
Open that sender and stay on Details.
Tick Sales Navigator if that LinkedIn account includes Sales Navigator.
Tick Recruiter if that LinkedIn account includes Recruiter.
Save, then open Contacts → Add contacts or Companies → Add companies.
Sales Navigator (Leads) and Sales Navigator (Accounts) stay locked until an Active sender has Sales Navigator ticked. Those cards say "Connect a LinkedIn sender with Sales Navigator to unlock". LinkedIn Recruiter says "Connect a LinkedIn sender with Recruiter to unlock".
If the card stays locked
Confirm the sender is Active, not Connecting or Challenge required. Confirm the matching checkbox is ticked on that same sender. One Active sender with the product unlocks that method for the workspace. If you ticked the wrong product, the card stays locked.
The full method list lives in LinkedIn import methods. CSV import does not need these checkboxes.
