I have multiple google accounts which I had seen in other forums caused some problems so I tried:
- sharing the sheet with my other accounts,
- logging out of all accounts and logging back in with my primary, and
- opening it in incognito with only my primary account logged in.
In each instance when I click Tools > Script editor I'm sent to a page that says "Sorry, unable to open the file at this time. Please check the address and try again." This is a google workspace account for which I am the admin.
Is there some sort of permission that I'm missing?
