Hello! I understand you're having trouble opening a chest in the Truck Simulator app on your iPhone, and that the chest still won't open even after you deleted and reinstalled the game. Let me help you fix this.

To clarify, when you try to open the chest in the game, does it show any response at all? Or does it just stay on the same screen without opening? Also, is this happening with all chests or just a specific one?

Meanwhile, here are some common steps to try that might solve the problem:

1. Restart Your Device: Sometimes, simply restarting your iPhone can help clear temporary glitches.

2. Check for Game Updates: Make sure the Truck Simulator app is updated to the latest version via the App Store.

3. Clear Cache/Data if Possible: On iOS, this is limited, but uninstalling and reinstalling usually clears cache. Since you've done this, let's move on.

4. Verify Your Internet Connection: The chest opening might require an active connection. Please ensure your iPhone is connected to a stable Wi-Fi or cellular network.

5. Check Permissions: Sometimes app permissions impact game features. Go to Settings > Truck Simulator and ensure all necessary permissions (like network access) are enabled.

6. Check for Game Server Issues: Sometimes chests rely on server-side communication. If the game's servers are down or under maintenance, this could prevent chest opening. You might want to check the official Truck Simulator social media or website for announcements.

If after these steps the chest still won’t open, there might be a deeper issue related to your game profile or a bug.

Please let me know about your current behavior with the chest and what you’ve already tried besides deleting the app, so I can guide you further.
