Hi @mrpowerus Mike, thanks for bringing this to our attention. Since the new features with service version 2025-05-05 were just rolled out yesterday afternoon, there are a few tenants that don't have these features enabled yet as they are gradually rolled out. There are a few workarounds as the features are being rolled out:

• Downgrade SDK to previous version
• Manually pin the previous x-ms-version without downgrading the SDK version by adding the kwarg api_version="yyyy-mm-dd" to your client constructors, which the last service version was 2025-01-05
• Move to a storage account that has the latest x-ms-version enabled, which would require more steps on your end so we don't recommend this

This will fix itself in a few days. Thanks!
