Hi there,

Yes, this is an Azure maps limitation.  They are limited to 30k polygons (this is not specifically a limitation for reference layers; it appears to be for the viz itself), and there is no way to modify.  MS's guidence was bacially, "don't use that many polygons".

Get started with Azure Maps Power BI visual - Microsoft Azure Maps | Microsoft Learn

Under limitations:
"

How many data points can I visualize?

This visual supports up to 30,000 data points.
"

Apparently this applies to the reference map as well as the Power BI viz itself.
