Enatega Customer App: Chat with Rider not receiving real-time messages and crashes on multiple send taps (Android) and empty msg being send on (IOS)

Nobody has claimed this yet.

Describe the bug
The chat functionality between users and riders is not working as expected. Messages from the rider are not received in real time, causing a delay or failure in updating the chat view. Additionally, when the "Send" button is tapped rapidly multiple times, the application crashes unexpectedly.

Steps to Reproduce:

Open the "Chat with Rider" screen.
Wait for incoming messages from the rider.
Observe that messages are not received/displayed in real time.
Type a message in the input field.
Tap the Send button rapidly multiple times.
Observe that the app crashes.
Expected behavior

Incoming messages should appear in the chat view in real time.
Tapping the Send button multiple times should not crash the app. Ideally, the button should be disabled temporarily after the first tap until the message is sent.

Smartphone (please complete the following information):

Device: [e.g. Samsung A15]
OS: [e.g. Android]
Browser [e.g. Chrome]
Version [e.g. 22]

No files or tests are named. Start by locating the Customer App's Chat with Rider screen and reproduce the delayed incoming messages and rapid-send crash on Android; also verify the empty-message behavior on iOS from the issue title. Done means incoming messages update in real time, repeated taps do not crash, and empty messages are not sent.
