I can't leave "notes" anymore on my customers account?

Hello Jo-hattonandberk, 

Welcome to the Community page, 

So we have had an update on Quickbooks and the notes section has been removed from there. To access the notes now you will either have to go to your practice> clients> (click on clients name) or logging into the client as a firm user and selecting "notes" from the Accountant Toolbox.
