3rd updated review, still no working distance filter. Noticed a pattern where you'll see a few people close by, then it will switch to people hundreds/thousands of miles away, even with the filter set to 20 miles. If you exit the app, then come back maybe in a couple hours, you'll magically be shown a few more people close by, then back to people far away. They're clearly filtering the results on purpose, because I've seen many of the close people before and know they're not new joins.
