When trying to connect with a deactivated user ID, the catch block throws a login timeout error rather than a user deactivated error.

What’s the best practice for handling login attempts from deactivated users?

Hi @tayloryun,  
If a deactivated user tries to log in, the SDK will through a 400300 error.

Hello, @Suhirtha_Ayyappan  
Can this be handled the same way in Flutter?

When connecting with a deactivated user using the project from sendbird-chat-sample-flutter, I could only handle LoginTimeoutException. How can I handle userDeactivated exception?
