Just upgraded mine. As far as I can tell it works exactly the same as before except there is now a “Hub” web portal and admin console you can use to give out access to your projects. Reading the documentation they said it would break existing shares. It prompted me that it would ask additional questions during the set up depending on what I was doing but I didn’t have any previous shares and did not get any additional questions. I would assume the 30 day grace period is to plan for this so you can get any shared documents straightened out afterwards. After the update it prompted me to “set up how I use fusion” by picking a module and then if I wanted it to start with a blank document or a previous document or a demo. That was annoying but didn’t reappear after I re-launched the app. All in all I don’t think this is that much of a concern. Looking at the web admin page the options it gives seem like they would be useful for someone sharing projects.
