Lost multiple messages in one conversation


I’m in Montreal, Canada. The ChatGPT 4 service was very slow and unstable this afternoon, I sent to GPT-4 for about 15 messages, and some of them need to retry multiple times before getting the responses. But just now, I found at least half of the messages I sent disappeared, and chatGPT seems doesn’t have the “memory” of what we said to each other for a long time, but it still keeps the beginning of the conversation. It’s so strange, feels like OpenAI did a rollback of DB at some point.

How can I get those lost messages back to the conversation? Is it even possible?

I have also experienced this same issue, I hope it will get resolved soon
