My Ads stopped showing after 3 weeks

[Germain Manuel]

HI Team, 

My ADs on my iOS app stopped working after 2 or 3 weeks. 

Please advise on how to fix this issue. as Ive tried the test ad ID and it still works, but the real test ID doesn't work anymore. and when I checked my aDmob account the ad ID status is ready. Im not sure what's happening here. Is there any updates that I need to implement or something?.  Please help.
