I have installed studio, done all mapping orchestration in Orchestrator and Uipath Robot settings. Able to run the package through Robot Icon, but not able to run through orchestrator as I am not seeing robot while starting a job.
Starting with this version (20.3) , you will no longer be able to start jobs or create triggers from Orchestrator on a Robot of type Studio or StudioX. In order to start processes from Orchestrator, you should use an Unattended Robot. Each Community account has 1 Unattended Robot included.
