Cannot continue previous chats in Google AI Studio history

Hello,

I’m experiencing an issue with my saved chats in Google AI Studio. For the past four to five days, I have been unable to continue my previous conversations.

When I open a chat from the history, the entire conversation log loads and is visible. However, the input field to add a new message is missing, so I cannot continue the chat.

I checked the token count, and the sum of input and output tokens for these chats is over 100,000, but it is still under the model’s context window limit (under 1 million tokens).

These chats are very important to me, and I need to be able to continue them based on the existing context.

Could you please help me understand what might be causing this issue and how I can resolve it?

Thank you for your assistance.
