Keep the gateway up-to-date in Installation & Maintenance. You can either do this manually when an update is available, or you can enable automatic module updates via the Settings tab.
There are 3 possible configuration options:
Daily - Updates will be presented and available for download on a daily basis.
Delay 14 days - After a release it will take 14 days before the update becomes available.
Delay 31 days - After a release it will take 31 days before the update becomes available.
Updating the Edge Gateway may take a while. The time it costs depends on the size of the package being installed and the speed of your Internet connection. Usually, it takes 10 minutes to 1 hour.
