Employee Engagement

My colleague shared an Employee Engagement project with me, but I can't seem to access the dashboard. Instead, I just get a message saying that it's not available. How can I get access?

I want to update my Parent-Child Hierarchy by uploading a file with the up-to-date metadata pairings, but when I perform the upload, the hierarchy metadata isn't changing. How do I get this to work?

I’m trying to send my participants dashboard invites, but when I try to schedule the message it says there are no participants available. Why is this?
