If viewing the event listing table, filter for the desired event and click the name of the event or select View button via the 3-dots menu. If viewing the event calendar, click directly on the event. For repeating events, it does not matter which occurrence is selected.
If the event cannot be found, ensure the correct calendar is visible. Event calendar visibility can be toggled from the side bar.
Regardless of the method chosen, the event screen will open after choosing the Go to Event button in the side bar. Select Edit event from the Actions menu in the top right area. A pop-up will appear where the event details can be edited.
See this article for more information on the fields an event has.
Helpful Tip
When viewing a repeating event, clicking on the date next to the title opens a calendar that allows quick navigation to any other occurrence within the repeating schedule. Only days in bold are valid.
