Ads work perfectly fine, but as soon as this setting is turned on (Settings > Privacy > Advertising) no ads will be served. The app actually was rejected a couple of times because the testers couldn´t get the rewarded video ad reward. (No video -> No reward) Took quite a while to figure out that it was this setting.
The question is, what to do now? I can only find rather vague information online that boils down to "It may work if you get a lot of traffic on your app and wait a while" and "There is nothing you can really do, just show a message urging the user to turn the setting off". Generally this is fine by me but it also isn´t exactly an elegant solution.
I thought that adding mediation/ad sources could improve the fill rate in this case (because more potential sources of ads will be requested before going into the error) but since all of them require adding SDKs it´s at best a major pain in the rectal region if it´s even possible in the first place.
I was hoping someone here has live iOS apps with admob/rewarded ads running and may know a solution.
