Global System Settings -> Controlled Updates

Umm.. https://cloud.sophos.com/manage/endpoint/config/settings/controlled-updates-endpoint

I selected 'Controlled Updates Manually - Currently selected'... and I can't exactly revert that setting..

https://docs.sophos.com/central/Customer/help/en-us/central/Customer/concepts/ControlUpdatesManually.html

----------------------

Furthermore.. any detail to how often it updates (time cycle/iteration perspective.. aka every 'x' minutes).. or anything.. is kind of lacking on the docs/help...
