ChatGPT Plus: no access to Code Interpreter/ Advanced Data Analysis

I have a Plus account, but in Settings/Beta features I have only Plugins as setting. What is the problem? How can I get Advanced Data Analysis activated?

“Advanced Data Analysis” is activated automatically when you are chatting with GPT-4 as it is out of Beta.

There is no need to activate it. It’s not a beta feature anymore. It’s incorporated in the main ChatGPT model. However, it is also available as a GPT in the GPT store, although I don’t see why you would want to use the Data Analysis GPT rather than the main ChatGPT model.
