The tooltip does not appear when I hover on a GANTT line when the report is published. It appears fine on the desktop. The issue has been tested from multiple machines and browsers. Does the GANT visual ever get updates? The version number hasn't changed in years.
We have received feedback from other users that tooltips is not displayed on Power BI Service. Can you provide detailed information about the version of Power BI Desktop and Power BI Service? Also does this problem persist if accessed through app.powerbi.com?
