The My Properties page is an area that displays all the properties you currently have access to. The properties displayed contain events within that you have been invited to interact with by an Administrator. To access your events for a specific property, simply select the property card displayed, and you will be taken to the My Events page (which displays the events you currently have access to).
Your current user role at each property can be viewed by hovering your cursor over a card representing a property you have access to. You can also view a counter of your pending alerts at the hotel.
