I am just starting my project, uploaded the requirements and then copilot said it was ready to make a plan. Click start, thinks for about 10 min and then comes back with "Stopped due to a problem. Please try again." Try again, copilot says it wants to perform the same task again, sometimes with slightly different wording, I click start and we go around again. I have been through many cycles of this burning credits each time. Is the system down? Am I using the wrong way? Or, do I just need to get my money back?
