I beleive I am finally all set. Not sure if these events are related but last night I got a canned email from "Lithium User" at Autodesk Support Team acknowledging this topic unanswered. I was provided three links to choose from:
Yes, I still need help
No, the issue is resolved
No, the issue does not need resolution
I clicked on Yes of course and went to sleep. I woke up this morning with an email stating that my "Autodesk Account is Ready". This is the email that I didn't get when I purchased Fusion 360. I should have, but I didn't. No wonder I was confused. This email was a good sign so I started Fusion 360 and no more Trial notice. Furthermore I logged into my Autodesk account and I no longer see the active trial and I do see the Fusion 360 subscription with 0 of 1 seats available. All of this tells me I am good...finally.
I'm not sure if this email (mentioned above) triggered the resolution or not, but I suspect so. I am all set and will mark this thread answered. I'll post a separate thread regarding clarification of "Enhanced" support with Ultimate. Maybe I just experienced it.
I must say, the fact that these threads are beign monitored for resolution status is reassuring. I'm feeling much better this morning.
