Native ad from various networks supporting image ad in an android app

Question

Have integrated admob sdk for Native Advance Ads in an android app.Ads are getting successfully displayed from network, image with "Install" app click to action button works perfectly.

Now have changed option from app to website as shown in screen shot

And have set 50% impression goal to display ads and rest for in-house ads which are just images.

But whenever the ads gets delivered to the app, there is blank white space as shown in the screen shot.

Have tried with different image dimensions but the result was same.

Have contacted to admob team but they said it wont be possible for Native ads with "Website" option.

Is there any network provider which supports Native ads with image(web) type format for android app and allows to run our own campaign?
