I purchased a apex classic from a fellow reefer. He provided me the sign in information for his account and using the fusion app i was able to update the email and password but cannot figure out how to update the username. I have tried to create a new fusion account but it states it is a duplicate email address, assuming because i changed the email on his existing account to my email. Do i need to change the email i attached to his account so i can create an account with that email? How do i remove his account and add mine to the unit? Is there a way to wipe all of the settings attached to the apex and start fresh? I am trying to do all of this from a iphone I currently dont have a computer.
