It happens that a scheduled intervention could not be done as planned, so there is a setting to display or not these interventions on the due date.
From the settings of the mobile application, go to the menu "List of interventions" and uncheck the option " Report if not done".
Thus, in the list of your interventions, you will only find the interventions planned on that day, with the due date.
And vice versa, if you leave the option checked, in the list of your interventions you will find all the interventions planned in the past that have not been carried out.
