No nb_uniq_visitors when using range

Since 1.11 when using VisitsSummary.get and you use a date Range, you won’t get nb_uniq_visitors.
Why is this? I assume because of performance issues…

What is the prefered method to get this number now? I need a range and a segment (visitIp).

Strange. I can remember doing that, but it was indeed missing in the current config.
