This article tells you how you can fix your work times.
If you have received a notification that your schedule has invalid/overlapping work times, you can fix it by yourself in the Work time settings. These overlapping work times can sometimes be found in projects that have been moved over from the old version to the new version of Sitedrive.
Here is how you can fix the work times.
1. Go to the Work time settings in your project phase.
2. Edit your work times by pressing the Edit button.
3. You can either remove the overlapping times by pressing the cross next to the worktime, or you can change the times. The default setting of the new Sitedrive is to take into account the lunch break by splitting the work times into two (7-11 and 11:30-15)
4. Save the changes.
