The automation cloud Orchestrator has no auto-update policies set for any machine and also not for any of the developer or Robot users. However both Studio and Robot were updated from 21.10 to 22.10, without any notice.
If the auto-update starts on a machine, there can be 2 reasons :
- The policy is activated. - Auto updating client components
- The user has an Automation Express license associated, which will trigger an update to latest version as stated here in the documentation Orchestrator Automation Cloud User Guide: Auto Updating Client Components.
