We are investigating delayed email delivery for some transactional emails, such as order confirmations and notifications. The delay affects recipients with Microsoft-hosted inboxes (Outlook.com, Microsoft 365). Other email providers are not affected. We will post an update as we have more information.
Starting August 31 at approximately 10:00 AM CT, we observed growing indexing queues affecting a subset of stores. During this period, newly created or updated entities may have taken up to 6 hours to become searchable in the Control Panel and storefront.
