We recommend deleting connections to data sources you no longer need. This makes it easy to identify which data sources are in use.
Click on your initials in the top right hand corner.
From the drop-down, select Admin.
Click the Connections tab.
Click the more options icon next to the connection you want to delete and select Delete connection.
By default, deleting your connection to a data source will delete all the associated widgets.
If you want to retain the widgets, check the option when deleting the data source.
Click Delete connection again when prompted.
