It's possible to delete, edit or update contacts you have saved in your contact overview. First, click on 'Contacts' in the navigation bar:
You will see an overview of all available contacts. Checking the checkbox next to 'Name' will select all contacts in the current view:
This enables you to perform actions in bulk, such as deleting all selected contacts at once, or adding them to a list:
Click on a contact to edit their details.
Your changes will be saved automatically.
Decide which accounts and languages should have access to an account:
Click 'edit' in the top right corner to add more accounts and their associated languages.
The contact is shared across these accounts, which means that changes made to the contact in one account will reflect in other accounts that have access to this contact as well. The exception to this is the 'Notes' field.
