Preserve your work
Copy your prompt and any useful output before refreshing. Note whether a request is still processing. Repeated submissions can create duplicate work.
Try a smaller request
Check your internet connection, then retry once. Break a long task into smaller steps and follow any upload or usage message shown in the interface. A tool may be temporarily unavailable even when the rest of the site works.
Report a reproducible issue
Include the page, approximate time and time zone, browser, device, exact error and steps to reproduce it. Remove personal or confidential content from examples. Explain whether the issue happens in one conversation or across the workspace.
