[Prototype]-Where did the blue line go and how do I get it back in XD?

[#1]

The blue line on three of my XD pages have disapeared. I think that it it causing linking problems between different pages. At least that is what some other forum question indicate. How do I get that blue line back?

Thank you.

Do you mean the connectors in Prototype mode? Is the workspace switched to Prototype mode and an artboard/element selected?
