Park SandDance and concentrate on simpler Custom Visuals for Power BI
The team that built SandDance clearly have significant design and technical talent. But meanwhile the simpler included visuals and Custom Visuals for Power BI are very poor - inconsistent properties / features, basic visuals like KPI icon missing, etc. Improvements to these seem to have stalled for many months now. I suggest you park the SandDance visual as "good enough" for now, and turn the team's talents to improving and extending Power BI's visuals and Custom Visuals where they could have a significant impact on a wide audience.
