I have seen this post in some site , I think you have also a same problem. see the solution below.
I am an app developer and published my app on Amazon store (also publish on google play store soon) but the problem is that admob banner ads are not showing from yesterday in my underdevelopment app which i am sending to you for check. I also download my own app recent app “Hamariweb Official” which was published on amazon but it was also showing no ads on that mobile phone. Also, i have no other mobile phone that i check my app on that. That’s a very terrible situation for me. I have used a website www.appetize.io on which admob “test ads” are showing but not real ads. Can you please check this for me? i will be very thankful to you.
- In my personal view , If you have made app through online platform like thunkable, appybuilder e.t.c. The main reason behind not showing of ads is the ads is not signed with unique certificate. You can sign your apk through “apk signer” app from play store.(note that signed with apk signer will not be published on play store).
- If you are building app from android studio and still the ads are not showing then try to make new ads units and use it in app, old adunits may not work properly, If you have done self click before, this also leads to not showing of ads , so create new admob account and use admob, it is the main solution i have researched.
- if you have done all from 1 , still not showing ads then create new admob account and try! this helps you 100%.
