Iframed Ads

I saw some discussion on this, but the solutions didn’t seem to work for me, so I wanted to start a fresh thread to see if anyone has had some recent success or workarounds.

We are going to host our own custom ads and call them in via an iframe in the footer. We have been able to get the ads in there, but they tend to link in the app and not out. Has anyone been able to do this? We want the ad to point to different webpages based on the ad, so this will need to be something we can swap out without having to change the app and resubmit changes to the apps store.
