With Create new day? ticked, Sprwt looks at the customer's last scheduled delivery date, finds the next available delivery date on one of the subscription's delivery weekdays after it, and creates a new open date there with the same number of days, meals per day and portion as the skipped date, with 0 meals selected and the same categories. The skipped date remembers which replacement it generated, so if you later Unskip the day you can tick Delete future delivery dates that were generated when this day was skipped to remove the replacement again (any meals already selected on the replacement are refunded automatically). Untick Create new day? if the customer should simply lose that delivery (for example when you refund them instead).
