If you confirm this is working then I can use the same fix for the other ad units. It takes a bit of time so I'd rather confirm the fix before applying it to the rest.
I'm not sure if you still want to know at this point, but I'm still getting the adsense ads.
Yeah.. fighting with Google on that, and I apologize that it hasn't been resolved yet. Adsense is a fallback for a "nothing else could possibly be shown" scenario. But GDNet+ ads are supposed to be shown in that scenario. Unfortunately Google doesn't provide a programmatic way to handle this. If it comes to it I'll have to turn off the fallback, which is a fairly large impact to GDNet unfortunately.
