The recent feature "Bookmark Navigator" is not working properly when I publish my report into an app. I can't really understand what is happening because when I open my report in the PowerBI Service,...
This same issue is happening to me as well. I believe this is related to the all around issues with the bookmark navigator. It wasn't rendering properly when it was first released (there are at least 2 threads about this). When I first published a report to an app in mid-November with this, it showed up - but now it is no longer showing up even though it is clearly present in the desktop report.
I would refrain from using this feature until the Power BI team has all the kinks worked out.
