Since Saturday we're expierencing severe issues with custom R-Visuals that use plotly in PowerBI service. The visuals won't load at all and just give the error message "Missing Dependency For A Known R Package. Package 'plotly' has a dependency that is currently unavailable".
Everything works fine in PowerBI desktop so my guess is that some R-libraries have been updated on the PowerBI servers that cause plotly to break. This has indeed been an issue and cause of visuals not loading anymore in the past.
