Where can I see a summary of booked nights and night limit for multiple listings?

You can add the "Nights Limit" and "Booked Nights" columns to create a custom report for listings:

• Night limits - If your listings have the annual night limit rule set, you can see the limit defined per calendar year.
• Booked nights - For listings that have the annual night limit rule set, you can see how many nights were already booked per a specific year.

These columns can be applied for the current year and the following year.

If you are not getting any data after adding these columns, this is because the annual night limit rule is not set for your listing for this specific year.
