the chat I started has been blocked and the conversation has not been saved in the chat history

After the problem with the code generation with Claude, today I find that the page is extremely slow. And it is not a problem with my computer or the Internet connection. The other pages work correctly. In addition, the chat I started has been blocked and the conversation has not been saved in the chat history. At first it seemed like a good option, although it requires a fee. These two aspects are very important when deciding to continue paying for the subscription.
