Please note: While the deployment of your Goodnotes license key does not require a reinstallation of the app, we would encourage all users to make sure they have an appropriate backup in place for their data before creating or modifying the Managed App Configuration. This can be achieved through iCloud Sync, Auto Backup or a Manual Backup.
Optional: If your license key is eligible for different versions of Goodnotes, you can add new configuration data to the App Config. See here for Goodnotes 6 and GoodNotes 5.
See below for a visual representation of the process:
Once all steps are complete, launch the app, accept the terms and you can start using Goodnotes! You’ll see the message regarding your key status as valid, please click OK to dismiss it.
Keeping data safe during installation
Despite the new licensing being in place to assist downloads of the app, there is no concern for any data loss, as the app would simply update in order to abide by the license key deployment. There’s no need to migrate any documents; your library will be there as is once you enter the license key. It's important to note, that we always encourage users to have a backup in place regardless of any changes and all end-users can do so via iCloud Sync, Auto Backup or a Manual Backup.
For Managed Configuration
Mobile Device Management software has the capabilities to send XML files that configure apps to managed devices within the network. Once the file is received by a managed device, the OS notifies the app that settings have changed and the app changes to match. You can use the same plist file written above for this process and for more information, see this developer guide from Apple.
