You can only see the time spent in the FC 24 Companion and Web App within the apps themselves. It will appear as a different value to your time in-game on a console or PC.
The total time and average time displayed in-game on console and PC doesn’t include time spent on the FC 24 Companion App and Web App, but console and PC time is factored into the total and average weekly time displayed in the Companion and Web App.
