WARNING: TRUECHART Visuals will be related to one another depending on if they are created in Power BI Desktop or Power BI Service, if you are using perspective commenting you must not duplicate TRUECHART visuals, otherwise the service will not work as expected.
Designing in Power BI Desktop & Publish to Power BI Service
If you are creating reports in Power BI Desktop, all comments here will be in development status. But if it is published to Power BI Service, comments from Power BI Desktop (dev status) will not be there.
In Power BI Service you can share the report and comment on it, comments will be stored as expected.
If you want to Edit the report with TRUECHART included then you have to download the report/open the power bi desktop dev file, you will only see "dev comments" if the report was not opened in edit mode in PowerBI service. After you edited everything and republish, the comments ("prod comments") in the service will be back.
Designing in Power BI Service
If you are creating reports only from within Power BI Service (and you are not using Power BI Desktop) as a self-service user with pre-defined datasets and only import TRUECHART, the comments are always in prod status. Comments are only intended to switch to dev status if you are downloading reports and open them in Power BI Desktop.
