Android 6 deprecation
The hardening framework used by the Nevis Access App dropped support for Android 6. There will be no more bug fixes or security updates for Android 6 / API Level 23 which leads to the potential of guards being or becoming bypassable as a consequence. Android 6 is more than seven years old and contains serious vulnerabilities, it is highly recommended to enforce a higher Android version to keep users safe.
