Android Facebook Native ads error: 1001 no fill on user device - facebook-audience-network

Question

Our application use Facebook Native Ad via mediation platform Mopub, and it works good, but we should move to another platform.
I've replaced SDK platform, using the same placementId and app_id and tested my application as Developer.
Everything works good in test mode with real ads also, but I cannot get ads on real devices.
I tried to implement Facebook Native without any mediation platforms(code in the bottom), but still have the same result.
So the issue is not in partner platform,but I cannot get ads on real devices. Facebook Native throws error: 1001 no fill
It looks very strange, because I have:
Application has real users and shows ads in the previous version.
Application in PlayMarket(but with the previous implementation) with same package Id, placementId and app_id.
Facebook has checked my app.
I can see requests from new and previous version.

In Facebook documentation "error: 1001 no fill" means:
This is a common error seen while testing, and relates to a "No Fill"
response; the most common reason for this is the user is not logged in
to the Facebook App when testing your mobile app or not logged in to
the Facebook mobile website when testing your mobile website.
Error 1001 - No Fill. May be due to one or more of the following:
- User not logged into Native Facebook App on Mobile Device(But real device logged into Native Facebook App)
Limit Ad Tracking turned on (iOS)(but this is not relevant for Android app)
Opt out of interest-based ads turned on (Android) (but I've turned value off)
No Ad Inventory for current user (What does it mean?)
Your testing device must have the native Facebook application installed.(but I tested on real device with real Facebook account)
Your application should attempt to make another request after 30 seconds.(but I'have the same result everytime)

What can be issue of it? Has somebody the same issue?
I'm afraid to make release without ability to be sure that user can see ads, because the main idea of our application is Advertisement.

Answer 1

step 1: goto play store download native Facebook app install and login
step 2: Then test your app "testing add loading success"
Other errors like : " FacebookAdapter: No fillI/TAG: No fill.I/Ads: Ad failed to load : 3"
then : goto Manifest file and add on application level : android:usesCleartextTraffic="true"
<application
.........
android:usesCleartextTraffic="true"
.......
/>
