What happened?

When using GPT4, a warning message "The previous model used in this conversation is unavailable. We've switched you to the latest default model" is seen on the webpage.
The entire conversation falls back from the black icon to the green icon means it's 3.5 version.

Steps to reproduce the problem

same code as before

from revChatGPT.V1 import Chatbot

chatbot = Chatbot(config={
  "email": "xxx",
  "password": "xxx",
  "access_token": "xxx",
  "session_token": "xxx"
})
conversation_id = "8eaeb9aa-2fc1-456b-a1ac-1fd8a93c88b0"
parent_id = "792a493c-ce54-4f11-a095-6c25dc983e3e"

question = "Remember , the prestigious election of stewardship has strict eligibility criteria. "
for data in chatbot.ask(
    question,
    conversation_id,
    parent_id
):
    response = data["message"]
