Hi there! I see you're able to receive messages on Telegram on your iPhone but can't reply because the keyboard isn’t showing up at the bottom of the chat. Let’s get that sorted out.

To start, could you tell me if this happens in all chats or just a specific chat? Also, have you tried any steps so far, like restarting the app or your phone?

In the meantime, here are some steps you can try to bring back the keyboard:

1. Tap on the message input area: Sometimes the keyboard only appears when you tap exactly on the text box. Try tapping once or twice carefully.

2. Close and reopen the Telegram app: Swipe up from the bottom (or double-click the Home button if you have one), find Telegram, and swipe it up to close. Then relaunch Telegram. This often resets interface glitches.

3. Restart your iPhone: Press and hold the side button and volume button to power off, then turn it back on.

4. Check for app updates: Open the App Store, search for Telegram, and see if there’s an update available. Sometimes new iOS versions or app updates fix keyboard display bugs.

5. Check Keyboard settings: Go to Settings > General > Keyboard on your iPhone and make sure keyboards are enabled properly.

6. Reinstall Telegram: If nothing else works, uninstall Telegram (don’t worry, your messages are stored in the cloud, so you won’t lose them) and reinstall it from the App Store.

If the keyboard still doesn't appear after these steps, it might be an unusual bug. Let me know what you tried and what happened, and we can explore deeper settings or check if there’s any known issue related to iOS 18.6.2 and Telegram.

Are you able to try these now and share any results? I’m here to help!
