Why can't I see all my upcoming reviews?

Luna shows the next suggested review date for each collection. For collections with a custom schedule this will be when all of the cards in the collection will be reviewed. For collections with a smart schedule, this will be for whichever cards in the collection are scheduled to be reviewed next.

At present, Luna doesn’t display any reviews beyond the next one. This is partly because Luna doesn’t create a fixed schedule of reviews for collections with a smart schedule. After each review is completed, cards are set their next review date depending on each card’s confidence score. So upcoming reviews won’t be scheduled until the current review has been completed.

For custom schedules, there is a fixed schedule of reviews that won’t change, and so this feature will be added to Luna in the future, and we will also think about how best to help plan upcoming reviews that are created using smart scheduling.
