If you have Location Manager, Location Administrator, or Administrator access then you can also set up email alerts so that you are notified when a room is booked.
To do this you log in to the web app, select on your name at the very top of the screen to access your own profile.
If you have access then you will see a link on the left entitled Email Notifications.
Click this and then you are taken to a menu where you can type the name of a location (it could be a specific room, floor or even building) and then select the type of notification you want (do you want to be notified if a room needs approval or every time it is booked etc).
Then click add. You can add as many of these notifications as you wish.
The process is also shown in the screen recording below:
