It seems that Azure Monitor REST API for SQL Databases and Storage changed functionality and broke my code 2 days ago. (west europe)

I had a simple REST call that would fetch all 1 minut metrics for a single resource in a single call. New preview api doesn't allow specifying more than a single metric per call which means that my code is now needing to make a call for each metric on each resource. It's probably 10x more REST calls than before.

This worked great with the old API, but 2 days ago it started to return BadOperation.
