Error: No Fill

**I dont know why i getting this error.**

**AdSetting:**

I use this in my startup file (index.js)

```
import { AdSettings } from 'react-native-fbads';
let hash = AdSettings.currentDeviceHash;
AdSettings.addTestDevice(hash); // i also used string from console too
```

**Usage:**

`import { InterstitialAdManager } from 'react-native-fbads';`

```
InterstitialAdManager.showAd(placementId) // i tried this format TEST_AD_TYPE#YOUR_PLACEMENT_ID
.then((didClick) => console.log(didClick))
.catch((error) => console.log(error));
```

Packages:

```
"react": "17.0.2",
"react-native": "0.67",
"react-native-fbads": "^7.0.5",
```

I also tried this dependency in gradle file:

`implementation 'com.facebook.android:audience-network-sdk:6.8.0'`

Reproduce the “No Fill” result from index.js using react-native-fbads 7.0.5 with React Native 0.67, then inspect the shown AdSettings and InterstitialAdManager usage alongside the placement ID and Gradle Audience Network SDK 6.8.0. Done means identifying the configuration or compatibility cause and recording a verified resolution.
