If you see the “Multiple different Google Accounts issue detected” message when opening the Artemis Sheets add-on sidebar, the issue is usually caused by having multiple Google accounts signed in within the same browser. Google does not support authorizing add-ons for more than one account per browser session.

​
Why this happens

When you’re logged into several Google accounts in your browser, Google automatically marks the first signed-in account as your default account. Google then uses only this default account to authorize any add-on you install, including the Artemis Sheets Add-on. So even if you switch to another account and install the add-on there, Google still authorizes it under the default account.

​
Example

Let’s say:
  • Account A = your default account
  • Account B = another signed-in account
If you install the Artemis Sheets Add-on while using Account B, Google still authorizes it under Account A. When you later open the sidebar with Account B, Google checks permissions, sees that the add-on is not authorized for this account, and shows:
Authorization is required
This is a long-standing Google issue and has been open on IssueTracker since 2017. It is documented on Google docs page here.

​
What still works?

You can continue using ART formulas normally, because they run under your default account in the background. However, sidebar features will not work unless you use the authorized (default) account:
  • Chat
  • Formula Builder
  • Templates
  • Settings

​
Quick fixes

Until Google enables multi-account add-on authorization, try the following:
  • 💡 Tip 1: Log out of all Google Accounts and log back in only with the account that has the Artemis Sheets Add-on installed.
  • 💡 Tip 2: Open the spreadsheet in an Incognito window and log in with the account that has the Artemis Sheets Add-on installed.
  • 💡 Tip 3: Create separate Chrome profiles for each Google account to avoid conflicts.
