Hi
I'm not sure whether this question fits here because it involves another platform which is the Power BI.
The first screenshot is a process map visualised on Power BI Desktop

The second screenshot is the same process map but published to Power BI cloud or service.

I think 2 remarks are, the first is while Power BI desktop can capture the '%', it is not the case when published to Power BI cloud.
Second remark is, the number font is somewhat less readable on Power BI cloud.
I'm not sure why this is the case but thought that maybe you may encountered this before.
