Test Device showing live ads

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,

Hi Oliver,

Thank you for contacting us.

If you’re using AdMob Mediation, test mode applies to ads served from the AdMob Network only and does not apply to ads served by other networks. 

Be sure that you've instructed your third-party ad source will serve ads in test mode. If you click on live ads served from a third-party ad source, you may receive a policy violation.

Testing instructions for third-party ad sources are available on Google Developer for Android, iOS, and Unity. Make sure that you have followed this article

Kindly provide us the following for further investigation privately via reply to author option:

• screenshot of the issue.
• app ID
• ad unit ID

 

I don't any third-party ad package only admob.

Sometimes showing test ads, sometimes showing real ads , sometimes no any ads.
Logs Showing this details;

Ad failed to load : 3

Ads Use RequestConfiguration.Builder().setTestDeviceIds(Arrays.asList("--------------------")) to get test ads on this device.

This logs showing but i closed and open later time i saw test ad , what's wrong?
