Hi there! I understand that you're experiencing an issue with the keyboard not working on the Citi mobile app for your iPad, even after reinstalling it. Let’s see how we can resolve this together.

First, can you please confirm if you are using any third-party keyboard or just the built-in iOS keyboard? Additionally, are you facing this issue with other apps on your iPad as well, or is it specific to the Citi app? These details can help narrow down the problem.

Meanwhile, here are a few steps you can try to get the keyboard working again:

1. Restart Your iPad: Sometimes, a simple restart can resolve minor glitches. Just hold down the power button until you see the "slide to power off" option, then turn it back on after it’s completely off.

2. Check for iOS Updates: Ensure your iPad is running the latest version of iOS. Go to Settings > General > Software Update and install any available updates.

3. Reset iPad Settings: If the problem persists, you can reset the settings on your iPad, which won't erase your data but will reset system settings. Go to Settings > General > Reset > Reset All Settings.

4. Check Keyboard Settings: Go to Settings > General > Keyboard and make sure that the settings are correctly configured.

5. Test Another App: Open another app that requires the keyboard (like Notes or Messages) to see if the keyboard is functioning there. If it's not, the issue might be with the device itself.

If none of these steps solve the issue, it might be beneficial to reach out to higher-level support or check if there are any known issues with the app in the Apple Support Community or Reddit.

Please let me know if any of these steps help or if you have any additional information that could assist us further!
