Subscription Issue - How do I fix?

I have a report saved in My Workspace.  Each morning when the data refreshes, I receive the email as expected with a snapshot of the information.

I shared this report with members of my team, they too subscribed, are licensed users and can see and use the report I created.  That said, they do not receive an email notification.

I am not sure what limitation is causing this.  Any insight?

Thanks!
