"Sorry, this conversation has reached its limit. Let's start a new chat."
I have been using Copilot for a while now, and it's not a tool that can be used for anything but simple short tasks.
Trying to use it for anything complex will result in the error you see. Which typically leaves the chat thread in a state where you can never reliably reopen it. So, all you work you have done is lost.
Medium complexity tasks where you have not hit that limit are equally compromised, as it's often impossible to re-open a thread and continue. As Copilot will hang when you re-open the thread.
The only workaround is to break everything into a simple task and keep track when you have had more than a few interactions and know to stop. As you are close to losing everything you have done.
Ask for a document summarizing where you are and then start a new chat from that document.
Copilot is simply not ready for anything more than simple short interactions.

this is absolutely not true. i use copilot daily, all day, every work day, and i use it to generate complex macros for excel workbooks. code that manages workflows across multiple workbooks located in different networks, some even isolated via VPN. i am learning to code at the same time, not because i am trying to learn, but because the complexity requires me to interact with code.
specifically, i can share a 500+ line VBA module that contains multiple macros and multiple helper functions, and that 1 module could be referencing and calling multiple other modules in different contexts.
you are using it wrong. this is not a judgment, just a fact based on my experience. if you smash your thumb with a hammer, the takeaway should not be that hammers are terrible and dangerous. the real takeaway is to get better at using the tools you have available.copilot is NOT perfect at this, but the relationship i have with that tool for code generation is the same a game director would have with his programming team: explicit, concise, and specific instructions must be given. any wiggle room you afford the actors responsible for implementation will be wiggled within, whether it is copilot or a human.

You are disrespectful, hoobadoo.
Copilot does have a space limitation within each chat. I also use it every day, all day, and one chat workspace will last from 6-10 days depending on the amount of chats. I have seen a warning message from Copilot normally when I have 3 responses left. In one case I was given a warning with 5 responses left.
The work I do is continual, so I have had to develop prompt scripts to extract the critical information from the predecessor chat to be loaded into the successor chat, but the continuity is not 100% and most cases I have to redirect the chat or reload rules I have established and documented in order for the chat I am working with to operate correctly as it was trained to do in the earlier predecessors.
That is much more work than should be necessary in this age.
At the very least, if there are space limits and Copilot has built code to warn the user they have a certain number of responses left, then Copilot should also have the capability to inform the user how much space they have. The fact the space is limited is unacceptable.
