ChatGPT Plus Plug-Ins Disappeared?

I am a original OpenAI user and was early on chatgpt as I was already using the GPT models before it. I was able to get access to GPT-4 model, browser plugin, and code interpreter for several weeks now. But, for some reason they just disappeared in the last day or two, and there isn’t the drop down selections anymore. The model in the url also look to have been downgraded to davinci-002.

Any reason why?
