What happens to the secondary master detail relationship if the primary master detail relationship is changed to lookup?

Hello,

I'm working through the Admin Beginner Module in Trailhead, and have come across an issue where I cannot view the Hover menu icon. However, I've already gone to the Reports and Dashboard seetings and checked "Enable Dashboard Component Snapshots", as well as going to Chatter/Feed Tracking and checked "Enable Feed Tracking" and all components for both Reports and Dashboards, but still don't have the Hover menu icon to be able to Follow or post a snapshot of by Dashboard component. Any thoughts?



Thanks,

Jessie
