You can access the events log from the Settings section (grey gear icon on the top right of the screen), in the Users/API management tab.
Here, for each user, click on the little clock blue icon at the right of the screen.
Estelle will show you the activity history of that user. This means, what did they do and what they did not do.
Use this feature to understand what happened when something unexpected occurs.
You will be able to understand:
who changed the price for a room
who inadvertently deleted a property
who edited the lease agreement end date
any other action that is done on Estelle!
