Why this happens
When you open a shared spreadsheet, the ART formulas run under the spreadsheet owner account.Example
Let’s say:- Account A = owner of the spreadsheet shared with account B
- Account B = opens the spreadsheet
Please sign in via the sidebar to use =ART functions.Even if account B logs into the sidebar, the ART functions still run under account A, so the same message will appear.
