Ganttmatic is provided by Mobilestudio

What to include

• What you clicked.
• What you expected to happen.
• What happened instead, including any message Ganttmatic showed.

Please don’t send your plan’s data or share your spreadsheet with us. We don’t need it, and Ganttmatic is built so that your data never leaves your sheet.

Before you write

Setup stops and names a tab

Your sheet already has a tab with the same name as one of Ganttmatic’s six tabs, say “Tasks”, and it isn’t a Ganttmatic tab. Ganttmatic won’t touch it. Rename that tab (double-click its name at the bottom of the sheet) and click Check again, or use a blank spreadsheet.

A teammate can’t open Ganttmatic

Add-ons need edit access to the spreadsheet. People with view-only access can’t use them, so send them a PDF (Export PDF in Ganttmatic).

Ganttmatic isn’t in the Extensions menu on a work or school account

Your administrator may need to allow the add-on first.

“Google couldn’t tell which of your accounts to use” or “Authorization is required”

This happens when you’re signed in to more than one Google account in the same browser. Google opens Ganttmatic as the account the spreadsheet is in, but sends its requests as the account you signed in with first. If that account hasn’t installed Ganttmatic, the plan can’t load. To fix it, do one of these:

• Use a separate Chrome profile for each Google account (click your profile picture in Chrome, then Add).
• Open the spreadsheet in an Incognito window and sign in only with the account that installed Ganttmatic.
• Sign out of all your Google accounts, then sign in with the account that installed Ganttmatic first.

Starting, copying or switching roadmaps

These are done by Google Sheets itself. See Everyday tasks, done the Sheets way.
