Hi, I got my vivoactive yesterday and had a real nightmare setting up an account, I need to delete the account under my primary email so I can get it set up once and for all properly,
I'm pretty sure you need to contact support to delete an account. However, in Express, what you can do yourself is to change the email currently associated with the account you want to delete to another address and then use the primary email for the account you really want to use.
