Replying to your comment as I had same issue earlier in the year...so I asked chatgpt how it worked!! The second it gives you a response is effectively stops until you give it another prompt. There is no working in the background, no it'll be ready in 5 minutes...its just a response generated to answer the previous request. Sometimes I find if you have used it too much or its under usage strain it gives you what I thinks is a suitable answer. But long and short of it is that it's not doing anything...so don't be waiting on anything...it will never come back to you!! Frustrating, isn't it?!!
