...but in reality this change has caused the native map visuals to become significantly less user friendly. There are posts on this forum almost every day describing various problems. A few workarounds have been offered, but they are less than ideal.

ARCGIS map is better in that regard, but has serious formatting limitations and doesn't interact properly with slicers.
