Can't find subscription links for taxonomy terms?

Think I have activated all that's necessary, and have had no probs getting Content type subscription links to show.

Is this working in 5x? I have checked the relevant vocabulary in Content Subscriptions, and selected Tags in the User Interface, and to show links on teasers as well as full nodes.

Allowed permission for all roles to subscribe to taxonomy terms in Access Control.

Selected links and block display on the relevant content type.

What am i missing? Thanks
