Hi Matilda,

Thanks for posting.

When you replace the APK file in the Hexnode repository, the policy will get updated automatically. You don’t have to re-apply the policy.
However, the way each device reacts to the update will be different. Certain devices support silent installation without user intervention. However, many devices require you to manually update when a ‘wrench’ symbol appears on the app icon in the kiosk.

Please use the link for further reference.

Cheers!
