Sophos Mobile (Central) App Protection

Hello everybody,

I want to configure a Tablet to be used in Kiosk-Mode at an industrial fair with an App-List of allowed Apps - e.g. Chrome-App.

The visitors should only be allowed to use Google-Chrome. My colleagues at the booth should be able to change Settings or launch Teamviewer by entering a PIN-Code.

For that reason i've set up an App-List to use it with an App-Protection-Policy to make Settings-App only available by entering a PIN-Code.

Even though Sophos Control App shows an App Protection for four Apps, none of these Apps lets me enter a Password neither a PIN-Code when opening them.

Also i'm unable to enter a Passwort in Sophos Control App.

Does anyone know a solution?
