Within Money Management, when you add an account you are given 2 options, one is 'Visible on Home' and the other is 'Visible on Financial Tools'. You can choose one or both of these options.
If 'Visible on Home' is selected, the account will display as a tile in the 'Accounts' section of the Home page.
If 'Visible on Financial Tools' is selected, the linked account will display in the Financial Tools section, like Budget and Net Worth, and account information, such as balances and transactions, will be available for Money Management.
