I guess we don’t know. According to the release notes:
Microsoft Flight Simulator 2024 flighting update 1.5.7.0 is on track to be released to the public flight groups on all platforms today (June 13). Please note due to some last minute delays with our publishing pipeline, it may still be several hours before the update shows up. We are working to resolve the issues with the publishing pipeline now, but are posting these release notes in advance as it’s unclear precisely when the update will become available.
