It never works, for whatever reasons, so it is useless to have it, and only causes confusion and fasle expectations
The auto-update of what...? Add-ons or LibreELEC itself?
(It's always so refreshing when people are clear in what they mean.)
You can disable both in their respective settings.
He probably means that nobody on staff (e.g. the release manager) ever remembers to update the auto-update config after releasing a new version so e.g. 9.2.3 is not pushed to people (auto-update is still on 9.2.1). Hence why I want to remove that piece of infrastructure and move the logic into the settings add-on so there's nothing to (forget to) update when releases are made.
just saying, 9.2.3 is broken for some RPi HW versions, therefore we never activate autoupdate because it could happen you end up at an blackscreen.
