On a fresh install of Fedora 35 Kinoite Software Update settings look like this:

However the current Fedora Docs (https://docs.fedoraproject.org/en-US/fedora-kinoite/updates-upgrades-rollbacks/) says it should be automatic, not manual: "OS updates in Kinoite are fully integrated into the desktop; you will be automatically notified when an update is available. The standard behavior is to automatically download the update (this can be changed from the update preferences in Software)." I would update the Docs myself, but I'm not 100% sure if the SIG intends for it to be automatic or not.

Furthermore, at least during the launch week of Kinoite, even though I had changed it to Automatic, and left my system running for a few days, running rpm-ostree --check would show commits from a week+ ago. Rebooted just to see if it's the case it just hadn't been applied yet but --check still showed the same week old commit. Still run into the same thing where I'll leave a system running for a day+ and --check will show I'm missing a few days old commit. Probably mitigated via Discover notifications once integration is supported.

Given that Discover integration with rpm-ostree is still a WIP (https://pagure.io/fedora-kde/SIG/issue/112) it might also be best to instead say something like "in future versions you will be automatically notified" with a link to Issue 112.
