I'm using a Tornado chart in a Desktop-based report. It looked a-ok and was about to publish. With the June update, the charts stopped being viewable on powerbi.com. Strangely, if I edit the report on powerbi.com, I can see the visual until I reload the page.
I saw that Tornado custom visual was updated in June so I tried to update my report, but it has the same issue. The Tornado demo PBIX file seems to work ok so I think my report is corrupt. I've tried a number of things to fix this (e.g, changed file extension to ZIP file and removed the custom visual). Short of re-creating the report (a multi-hour process), how can I fix this?
