Hey there! I understand that your Hunting Sniper app is getting stuck at 50% loading after trying to email. Let's see if we can sort this out together.

First, let's try a couple of simple troubleshooting steps:

1. Check Your Internet Connection: Make sure you have a stable internet connection. You can try switching between Wi-Fi and cellular data to see if it helps.

2. Clear Cache and Data: Sometimes, accumulated cache can cause loading issues. Here’s how you can clear the cache and data for the app:
- Go to Settings on your Android device.
- Scroll down and select Apps or Application Manager.
- Find and tap on Hunting Sniper.
- Tap Storage.
- Then, select Clear Cache. If the issue persists, you can also select Clear Data, but note that this might reset your progress in the game.

3. Reboot Your Device: A simple restart can often resolve minor glitches. Turn off your device, wait a moment, and then turn it back on.

4. Update the App: Make sure you are using the latest version of the Hunting Sniper app. Go to the Google Play Store, search for Hunting Sniper, and see if there’s an update available.

If you’ve gone through these steps and your app still won’t load past 50%, we might need to consider uninstalling and reinstalling the app. Here's how to do that:

- Go back to Settings > Apps.
- Select Hunting Sniper and choose Uninstall.
- After it’s uninstalled, head to the Google Play Store and reinstall the game.
