Hey Team,
I am currently integrating the iOS Messaging Zendesk SDK by initialising the SDK with the channel key and launching the ZDKMessaging.instance.messagingViewController on successful initialisation.
I am running into an issue there - The zendesk chat opens up with previous message history and flows ONLY on the first launch of the zendesk viewcontroller instance.
If I close the zendesk chat, and re-open it, I see the zendesk chat view controller with a no previous messages. I can type the message in the input field at the bottom, however, once I hit send, the message isn't seen in the chat window.
Here is the attached screenshot of how the blank zendesk chat view controller is seen on the second instance.

Hey Amogh,
Sorry you're running into issues! Can you provide the code of your ViewController and any corresponding delegates so we can take a look?
Have a wonderful day!
