Resolving Existing "usage has been exceeded" Messages
After purchasing or modifying your plan, and updating your license in Google Sheets, you may still see an error message like "SheetGPT usage for firstname.lastname@example.org has been exceeded" in some of your cells. This occurs because Google Sheets has not told SheetGPT to re-evaluate that cell yet. There are a few things you can do to try and refresh these cells:
Refresh the current browser page. Google Sheets will sometimes force cell re-evaluations at this point
Copy the cell's formula, delete the cell contents, then paste the cell formula back in to get a fresh GPT evaluation
