title: I can't run my script for a google sheet, how do I verify app?
body: <p>My script uses reference cells linked to an external sheet to hide or show rows as I need them. It says I am not an authorized user. I don't own the sheet but am granted editor permissions. It's worked a ton before, I don't know why this is happening now. Please help!</p>
  
  <p>Thanks in advance!</p>
