The app@sharepoint principal is not resolving in newly created tenants

Quantumrunner  Here is the latest from Microsoft support.  I answered some basic questions about my particular use case and am awaiting their next reply:

We would like to inform you that the Account app@sharepoint is related to the SharePoint Applications (Auditing logs/Virus check), it is a system account, belongs to the SharePoint Farms infrastructure, it was created to run on all Site Collections/Personal sites to collect auditing information. When the user provides some changes for his own Site Collection, or enables features or activates the site Auditing logs, his own account does not have the write permissions on the SharePoint Farm and this account it will be used to run and collect all the necessary information to be provided to the customer. Microsoft has set up a few security accounts to run in all Farms, in order for our customer to do some tasks, and get the required information. Also it is necessary for user security, for these accounts to always track the Site Collection searching for viruses that can be uploaded into SharePoint. Microsoft will not change that, all Farms have the same configuration and this same system account, and all Site Collections will use this account if they need to do it.
