Test Device showing live ads

[Oliver Gründel]

Hi all,

a couple of days ago I implemented advertisements in my Android App. At first I tested my app using the known Test Ad Unit IDs. Came release I switched out the Test Unit IDs with my live Unit IDs and set up my testing phone as a test device in my AdMob account. This was two days ago and my Testing device is still showing live ads with no Test Ad badge. I've double checked that I have correctly entered my Advertising ID but cannot find a cause as to why this is happening.

Thanks for any help,
