Popcash-request for sharing experience

[deppstar]

Hi, anyone wants to share their RECENT (last 6 months) experience with Popcash in pop advertising. I use to have little luck there but now is a disaster so I'm wondering if there's some tip to consider (i.e.specific verticals, offer kinds, geos to stay far from, generic do and donts ). I love their dashboard, their team is very polite and professional and also met someone at convention and had a good feeling but ...wow -92% Roi ..., 5 geos tested, something is wrong here..there's not much to optimize
