To begin importing your Microsoft To Do tasks into Amazing Marvin, start by clicking on the menu icon (☰) in the top right corner in the main view. Select "Account" and then navigate to the "Import" tab.
On the Import page, you'll find a dropdown menu. Click on the menu and select "Microsoft To Do" from this list. Once selected, you'll be guided through the process of connecting your Microsoft account to Amazing Marvin.
You'll need to log into your Microsoft account and grant Amazing Marvin permission to access your Microsoft To Do data. After you've authorized the connection, Marvin will load all your data from Microsoft To Do and clicking on the "Import" button will add that data to your Inbox category in Marvin.
Cleaning up your data
Marvin has its own model of how to organize your tasks. So the first thing you want to do after importing is to "Marvinify" your imported data.
Go through the Master List set up guide to understand how your Master List should be organized.
