You can access service information for an Event by either clicking the Events tab at the top of your dashboard > clicking the Date/Time of the Event you wish to see details for, or by clicking the Schedule tab at the top > clicking the Event Date/Time block to view the worship flow for that Event. Both take you to the same page.
From there, you will see tabs above your flow labeled Event Flow - Assignments - Stage Setup - Rehearsal. Simply click the tab you wish to expand details for.
If there are notes that you need to see for either all people or you specifically, click the dropdown arrow to the left of the time of that Element within the Event Flow tab to see/add notes.
