Hi there! I'm sorry to hear that you're experiencing issues with Zoo 2 crashing. Let's work together to get this sorted out.

The message "you are no longer logged into the game" can happen for several reasons, so I'll need a bit more information from you. Can you tell me if you've noticed any particular patterns before the crash occurs, such as certain actions or areas in the game? Additionally, have you recently updated your app or your device's operating system?

In the meantime, here are some general steps we can try to resolve the issue:

1. Check for Updates: Make sure that Zoo 2 is updated to the latest version. Sometimes new updates can fix bugs that cause crashes. You can check for updates in the Google Play Store.

2. Clear Cache and Data: Clearing the app's cache can help resolve performance issues.
- Go to your device's Settings.
- Select Apps or Applications.
- Find Zoo 2 and tap on it.
- Tap Storage, then hit Clear Cache and Clear Data (note that clearing data might remove your progress unless it's saved to your account).

3. Reduce Animations: Some users have found that reducing animations helps with crashes. You can try this in the game settings if it’s available.

4. Check Network Connection: Ensure you have a stable internet connection, as dropping out can also lead to being logged out.

5. Reinstall the Game: If the issue persists, you can uninstall and then reinstall the game. Just make sure your progress is saved before doing so.

Please try these steps and let me know how it goes or if you need any further assistance! I'm here to help.
