Issue fixed about a week of dealing with it. Not sure if it was something I did, was fixed on the back end, or if it "fixed itself." I was eventually able to go through all the welcome screens and everything worked correctly, with only a few (intentional?) changes that were likely a part of the update (if you pull down on the right top of screen then you can gain access to controlling Bluetooth, airplane mode, flashlight, etc. and if you pull down in the middle then you see your notifications).

My home button is gone, just has the back button shows up at the bottom. And I cannot thumb down from the top to access anything. Also, my "settings" won't open, so I don't even know what I can change. And all my icons are smaller than before.

This "update" is absolutely awful and frustrating. I've seen some say it's trying to be more like Apple and I agree with the comment, "If I wanted an Apple then I would get an Apple."
