hi nanek, i'm also getting problems with prebid native. I'm uisng multi format units and the majority of the time native ads dont render with all the details in them , i think becasuse its over send limits. So I'm looking at you script here but can this work with multi format units, as i already difine a renderer for the video "oustream" mediaType

@spormeon did you try using native placeholders? Placeholders solved my issues with native ads.

@jbartek25 i am trying that, but still getting probelms, my probelm seem to be that ehen i get more than 1 bid on a native ad, its trying to send all the bids adid on the targeting. I'm not 100% sure i have my native creative propeply setup as when i get 1 bid and it sends that 1 bid targeting, some links work, others dont. Would you have sample "native styles" code that works 100%, I can try that, see if it eliminates anything.

more on my prob here: prebid/Prebid.js#4059
