I am just learning how to use Google App Script for some dummy data in a Google Sheet and I keep running into "This app is blocked This app tried to access sensitive info in your Google Account. To keep your account safe, Google blocked this access." Less Secure App is already ON, and I don't know what else to do. I'm just trying to run a darn SpreadsheetApp.getActiveSpreasheet(); and I can't even get through that. Please help, so frustrated with Google. Thank you.
Edit: I can't even run Google's own "your first script" tutorial because of this issue.
