• Cells show Exceeded maximum execution time, a 429 rate limit or Service invoked too many times: wait a minute (or until the next day for the daily quota), then click Retry errors. Only the failed cells are re-run; cached results are kept.
• Cells show #NAME?: the formulas are not enabled, click Enable GPT formulas instead.
• Cells show an out-of-credits message: top up or upgrade first, then Retry errors. See Common errors.
