Hi Guys - Anyone have experience with responsive ad units? I'm running some tests before converting my entire site, and need to get responsive ads working. I'm having all kinds of trouble. I've read the DFP documents ( https://support.google.com/dfp_premium/answer/3423562?hl=en&ref_topic=4390040 ) but to no avail. 

I noticed a lot of people talking about selecting the ad unit size "responsive" when creating an ad unit. I don't even have this option. I have every size imaginable, just not responsive. 

Any help is appreciated.

Never mind, I got it working.

Oops, spoke too soon. I still don't have it serving the right sized ads.

Man I've been having the same issue too.  Hope somebody here can lend some insight.

I use AdSense responsive ads. They… just size themselves.

I think for alignment purposes I created a DIV at the top and made it 80% width or something with CSS, but on the sidebar it's just a responsive ad block from the AdSense code they supply.
