@Vazgen Zohranyan Are these experiments or jobs submitted from the UI or the SDK? Are you using any of the preview features that are available from the UI to submit these jobs? Does the jobs tab not display the jobs that are running/complete?
I think it might be easier to report with the screenshot of the notification through your azure ML portal using the smiley icon on the top right hand side. This will help the service team with all the required details of your subscription and workspace to check the job details.
