I'am using the last version of Power BI and when a click in Publish, Power bi make the habitual steeps and "publish"... But when I go in the workspace the report is not updated or created. I have teste in a shared workspace and my workspace.
Can you publish your report to Service normally now ? I tested with May version , publishing report to Service worked well , you can see the screen below . Maybe you can uninstall Desktop completely and then re-download the latest version from download center and try to publish the report.
