Question about ads

Hi, I’m live now with Instant Articles on FB and all seems to be working ok. I still have to manually go in and fix Instagram embeds, but that’s not a huge problem now. One question I have though is about ads, I created 3 ad units in the Facebook Audience Network and set each to “native” “optimize for fill”. Then I put the IDs of those ads in your backend, but when I view the article in the FB app the ad space just shows up as blank.

It may be a problem with the code generated. This is the code created by the plugin

<!-- Audience network placements --><section class="op-ad-template"><!-- First ad is default ad, will be reused if not enought ad placements available --><figure class="op-ad op-ad-default"><iframe width="300" height="250" style="border:0; margin:0;" src="https://www.facebook.com/adnw_request?placement=402794813220748_591640344336193&adtype=banner300x250"></iframe>
					</figure><figure class="op-ad"><iframe width="300" height="250" style="border:0; margin:0;" src="https://www.facebook.com/adnw_request?placement=402794813220748_618400388326855&adtype=banner300x250"></iframe>
					</figure><figure class="op-ad"><iframe width="300" height="250" style="border:0; margin:0;" src="https://www.facebook.com/adnw_request?placement=402794813220748_618400451660182&adtype=banner300x250"></iframe>

But it seems to me that lines like this

https://www.facebook.com/adnw_request?placement=402794813220748_618400451660182&adtype=banner300x250

should actually be this instead

https://www.facebook.com/adnw_request?placement=402794813220748_618400451660182&adtype=banner300x250

Any ideas? Thanks!
