For split billing charging sessions, prices are never displayed in the Smappee App. 
However, you can find them in the Smappee Dashboard.

Login to the Smappee dashboard (https://dashboard.smappee.net).
Select the board “EV Line” from the menu on the left.
Scroll down on the right side until you see the card title " Sessions of …"

This card allows you to :

• Click the download button to export sessions as an Excel or CSV file.
• Set the desired period via the calendar button
• Select the activation method of the charging session ( see Session activation methods – Support )
  Here you choose between split billing sessions and whitelisting sessions, if available.
• Use the three-dot menu in the top-right corner to add or remove columns based on the information you want to see.
• Sort columns from high to low
• Adjust the number of sessions per page and navigate between pages as needed.
• Use the gray scroll bar on the right to view more sessions, if available.
