Please don't update the spreadsheet - it's automatically generated from the app. You can update the app yourself if you've saved your letterkey (the string of letters and numbers that the app gave you when you entered your letter), or if you didn't save it, you can reply to this comment with the change you made, and I'll do it for you. (Or DM me for your letterkey and I'll send it to you, and you can do it yourself.)
