I am getting the error 1001 No Fill
when trying to load real ads for testing. I'm able to load test ads by adding AdSettings.addTestDevice(deviceId);
and have fulfilled the steps as per Facebook testing guide:
- Native Facebook Apps installed in device
- Developer/tester account logged into the native Facebook app
- Logged in with Facebook account in my app
- Deselected "Opt out of interest-based ads" in Google ads setting
It also mentioned that we are able to test with real ads on testing stage and it is a more recommended method. Why am I still getting the error? Is there any other possible factor causing the failure to test with real ads?
