Unfortunately, you can't tag people when you create a Linkedin post via HS. So I needed to write a post directly on Linkedin, in order to be able to tag @ people. Unfortunately (again), I can't add this Linkedin post as an asset to a campaign, since it wasn't created by HS. I understand the first issue (not being able to tag people) is an issue coming from Linkedin itself, but the asset issue could be fixed by HS. Thank you.
