Comprehensive coverage and cost-savings with Microsoft Sentinel’s new data tier

The pricing for Auxiliary Logs disappeared from the Azure Pricing Calculator (https://azure.microsoft.com/en-gb/pricing/calculator/) and the Sentinel Pricing Page (https://azure.microsoft.com/en-gb/pricing/details/microsoft-sentinel/) as well as the Azure Monitor Pricing Page (https://azure.microsoft.com/en-gb/pricing/details/monitor/).  Instead we're told to 'Please reach out to your Account Team for additional details'.  Unfortunately, the pricing does not seem to be available and a ticket with both the Billing and Sentinel teams in Microsoft Support came to a dead end.  Would you happen to know why the pricing for Auxiliary Logs is proving so difficult to find?
