Check your settings. There are two ways to show or hide prices:
1. Via the settings: Open the hamburger menu at the bottom right of the app and tap List settings > Prices. These price settings can also be used as the default for any new project.
2. Via the menu that opens when you tap the three dots in the top-right corner of the open list. Here, you can manage the price information for the list you are currently working on.
In both places, you can also specify whether prices should be displayed inclusive of VAT or exclusive of VAT.
