This Secrets Manager release has the following fixed issue:
When users of business groups accessed the Secrets Manager user interface, the
do not have permission error occurred when trying to perform actions in Secrets Manager. This happened even though the master organization (or a parent of a business group) had the API Manager Environments entitlement.
FIX: If the master organization has the API Manager Environments entitlement, users of the child business groups are now able to access Secrets Manager functionality.
