Hi there! I see you're having trouble with the Tower War app saying there's no internet connection on your iPad with iOS version 26.3.1, even after updating iOS and reinstalling the app. Let's get this sorted out together.

First, to make sure I understand, are you connected to Wi-Fi or using cellular data when this happens? Also, do other apps on your iPad have internet access normally, or is this issue happening only with Tower War?

Once I know this, we can proceed with targeted steps. Meanwhile, here’s a basic checklist we can try:

1. Check Network Connection
- Confirm your iPad is connected to a stable Wi-Fi or cellular network.
- Try toggling Airplane Mode on and off briefly to reset connections.

2. Verify App Permissions for Network Access
- Go to Settings > Tower War and ensure the app has permission to use cellular data if you aren’t on Wi-Fi.

3. Disable VPN if Active
- If you have a VPN set up, try disabling or removing it. Sometimes VPNs interfere with app connections, even if turned off.

4. Reset Network Settings
- On iPad, go to Settings > General > Transfer or Reset iPad > Reset > Reset Network Settings.
- This will erase saved Wi-Fi passwords so have those ready.

5. Check for any iOS or App Background Restrictions
- Verify Settings > General > Background App Refresh is enabled for Tower War.

If after these steps the app still shows no internet, there might be a known compatibility issue or server-side problem for iOS versions similar to yours. Some Tower War users have reported issues tied to iOS and ad-related components, which developers are working to fix1.

Let me know what you observe with the above or if you want me to guide you through any of the steps in more detail. Are you connected via Wi-Fi or cellular currently?
