Facebook Banner Ads not showing

Today I update my app on play store. The app is live now. I test my app for ads work or not. Facebook interstitial ads are working but banner ads not working.

Before the post, I search in the community and found some topics but banner-ads-not-appear-after-installation, OR the-ad-banner-doesn’t-work “This site can’t be reached” showing the error message.

Check your placement ID.

You should use banner placement id for banner and not native banner id.

It is my old project. Before update ads are working but After update ads not showing.
