Open it from the Dashboard alert "You still have N meals that have not been selected from customers on subscriptions" (View Report), the Auto Select Meals fulfilment card, or directly at /admin/changeusermeals?dd=YYYY-MM-DD. It shows Total Unselected Meals and Total Subscriptions for the date and a table with Subscription (customer, with a Details toggle showing their category, allergen and dislike badges), Plan, Total, Selected, Missing, an Auto Select Meals button per row and Manually Select Meals (Checkout As). Auto Select Meals for Everyone runs auto-selection for every listed subscription after a confirmation. After the run you are returned to the Dashboard; any subscriptions that could not be filled are reported there.
