Why “Fetching…” Stays
A Shovels formula doesn’t call the API itself. It marks its cell as waiting. After an edit in the Sheet, the edit trigger of the user who set the key fetches every waiting cell.
After a refused key, no credits left, the rate limit, or a server error, edits leave the cell alone for 10 minutes. Fetch waiting formulas tries again at once.
