Thanks everyone for your support and votes! We’re working on enabling commenting for dashboards and reports in the Power BI service soon. Stay tuned.Erika Steffins commented
Agreed, I think it would be very useful for users to be able to comment with questions on the dashboards/reports. It would also be a nice addition to this if they could then *tag* people in the comments by email address or name and then that person would get an email notification of the comment.
