Make sure that you mark both the Ongoing and Display on Website fields while creating new Jobs in Salesforce. The jobs marked with Ongoing and Display on Website are displayed on the V4S Kiosk application.
If you have already logged in to the V4S Kiosk application and then mark the Jobs as Ongoing and Display on Website, please logout and re-login to the V4S Kiosk application on the device. We suggest you to log out and re-login to the V4S kiosk application on the device is because any configuration changes that you make in Salesforce reflect only if you logout and re-login to the app on the device.
