Depending on the strength of your Wi-Fi network, your iPad may take time to update changes made in the admin. In the first instance, you could try the steps listed below.
1. To update the changes on the iPad, go to Configuration (top bar menu) > Terminals (side bar menu) and click the Send Configuration button (2) for the relevant terminal. The VPass App should then update within a few moments.
If the iPad is still not updating try deactivating and reactivating your iPad.
