    Thank you for the support and advice. I ended up excluding some regions to stay below the 30k polygons threshold which is working fine.

This issue is likely related to rendering limitations in the Azure Maps visual within Power BI. When working with large GeoJSON files containing thousands of polygons, some features may be silently dropped due to performance constraints.
Here are three concise recommendations:
  1. Simplify the polygons using https://mapshaper.org/ with the command simplify 10% keep-shapes to reduce the number of vertices while preserving the overall shape.
  2. Split the GeoJSON file into smaller segments (e.g. by region or category), as files exceeding approximately 5MB may not render fully in the visual.
  3. Validate geometries to ensure there are no topological errors such as self-intersections or improperly closed rings. The clean command in Mapshaper can assist with this.
For further details, refer to the official documentation:
