Navigation bar glitch

We found that when a user opens ZenDesk chat and goes back, the navigation bar blinks/flashes once with blue colour.
After that, it starts to happen in both ways, on the appearing chat screen and disappearing.
Condition:
iOS 15.5
ZendeskChatSDK 2.12.0
Chat pushes in UINavigationController as the second (not first) viewController.
The root view controller was presented as a modal.


Is anyone has the same issue? If so, what is your workaround for this?

    Hey Maxim,

    Can you share the code snippets of how you're initializing the sdk and presenting the view?

    Thanks!

    Hey Eric,
    thanks for helping.
    The next code is from a demo app that also has this glitch but visibly less. 
    to see it better, use slow animation on a simulator and use a dark background for the navigation bar.

    Chat.initialize(accountKey: accountKey)
    Chat.instance?.resetIdentity(nil)
    let chatEngine = try ChatEngine.engine()
    let chatViewController = try Messaging.instance.buildUI(engines: [chatEngine], configs: [])
    navigationController?.pushViewController(chatViewController, animated: true)

    The code is a bit complicated in our main application but mainly the same.

    Chat.instance?.configuration.department = department
    let formConfiguration = ChatFormConfiguration(
        name: .required,
        email: .required,
        phoneNumber: .hidden,
        department: .hidden
    )

    let chatConfiguration = ChatConfiguration()
    chatConfiguration.preChatFormConfiguration = formConfiguration
    chatConfiguration.isPreChatFormEnabled = some logic

    let messagingConfiguration = MessagingConfiguration()
    messagingConfiguration.name = answerBotName

    let chatEngine = try ChatEngine.engine()
    let viewController = try Messaging.instance.buildUI(engines: [chatEngine], configs: [chatConfiguration, messagingConfiguration])
    viewController.overrideUserInterfaceStyle = .dark
    navigationController?.pushViewController(viewController, animated: true)

    P.S. Not sure how it's important but the viewController who presents the chat should be presented modally
