Microsoft Dynamics CRM/CE Address Suggestion not appearing

A recent issue we came across was dealing with the address suggestion that is a feature of the Sales Hub and Field Service app in Dynamics 365. We have a custom security role that was giving access to all of our sales people. When editing or creating an account after the user types in the street 1 and city/zip the address suggestion modal is supposed to appear. During testing we were able to see with system admin access it was still working which narrowed it down to a security issue.

After some troubleshooting and process of elimination we were able to figure out that under Custom Entities there is a table called 'Scheduling Parameter'. When we toggled the Read permission for this table we were able to see the address suggestion modal with our salesperson user. Hope this helps, contact us for troubleshooting help!
