 **Important**: To enable feed updates you will need to enable either [Nextcloud system cron](https://docs.nextcloud.org/server/latest/admin_manual/configuration_server/background_jobs_configuration.html#cron) or use [an updater](https://github.com/nextcloud/news-updater) which uses the built in update API and disable cron updates.
