Booking activity is a place where you can find the history of changes made to the booking by you or people from your organization. Additionally, you will also be able to find who created the booking and what were the initial settings.
This helps you keep track of changes and people's responsibilities, especially if you have a large team with a lot of people to book.
To find this activity, open the booking → click Show booking details → select Show history.
The timeline will display the following changes on the booking:
time and date
automatic tracking turned on/off
custom fields changes
as well as who made the changes and when.
