I need help logging into multiple seats of Fusion 360. I currently have purchased 3 seats of Fusion. When I log into my account, I then add a user and assign the products to that account and then invite the person. I get the email sent to me with instructions to setup a new account. When I do that, I only get a 30 day trial. Why am i not getting the full license I paid for and that was assigned to my email? Please help
