To get to a client's daily logs, first click on "Clients" in the top menu. You'll see your list of clients in this section. Select the client you're interested in and then click "Daily Logs" in the sub menu.

If your team has been recording logs with the mobile app, your client's daily logs page might look something like this.

If it's empty, it might be that no logs have been recorded yet in the app or that you need to change the date range using the date picker.
