Getting "No fill" error only if the app is installed from Google Play

[bunyaminsg]

I have developed an app and integrated with admob. When I install the release apk to a device everything works fine. It also works when installed the app from play store to a device that is registered as test device in Admob.

However, in any other device that installed the app from the Play Store, ads are not shown and LOAD_FAIL event fires with error code: 3 and reason: No fill.

• My admob profile is complete. (I have an older app with working ads)
• I have the <variable name="PLAY_SERVICES_VERSION" value="11.0.0" /> dependency in the config.xml file. (I also tried the version 17.0.0)
• I created app-ads.txt in my developer website
• I tried to create new ad units and use them
• I didn't try to remove the app from the store and create another one as it takes too long to be confirmed.

I appreciate if anyone encountered a similar issue could help. Thanks in advance.

In despite of working when installed via apk case is strange, it started to work after 8-10 days.
