iTunes Connect Test Flight won't play AdMob Test Ads

Question

I just double checked in my Xcode Project and the build I uploaded to iTunes Connect has AdMob test ads ON. However, this same build during Test Flight's Internal Testing is not playing the AdMob test ads, it's playing live ads.

How do I make it play AdMob test ads during beta testing?

Answer 1

To get test admob ads, you need to specify test device. otherwise, only in simulator it shows test ads.

To specify test device :

    GADRequest *request = [GADRequest request];
    request.testDevices = @[ @"2077ef9a63d2b398840261c8221a0c9a"]; //my iPhone's UDID
    [self.bannerView loadRequest:request];
