To activate the track reservation in the Mobile App, we will go to:

System → System Configuration



In the menu on the left, click on Web-APP and later on Mobile App.



We will go down the screen until we see the Sections Board Administration options where we will press the option of 'View Tournaments section'.



Keep in mind that we also have to have the "Visible Web" option selected in the championship tab.
For that, we will go to the championship page that we want to see on the web, we edit it and go to the option "Additional datum" in the menu on the left, and enable the option "Visible on Web". As shown in the picture.
