Hi,
Thanks for posting in Microsoft MECM Q&A forum.
==>the collection we deployed it to has a limiting collection of machines with 1909 OS.
Are you using a dynamic collection for the collection of machines with 1909 OS? If yes, the value for schedule a full update on this collection is 7 days (1 week) by default.
So it may take 2 weeks (1 week for the rerun behavior and 1 week for the dynamic collection full update schedule) plus random delay to update the deployment statistics.
Hope it helps. Thanks for your time.
Best regards,
Simon
