Why did you leave the beta when the beta automatically rolled over to the official OTA?!
I reckon that's why it's not showing the update on your handset.
You could Odin flash the official release I suppose, this would likely mean you need to wipe the device during the process of course.
I "Odined" the stock UK Nougat straight on top of my XEU marshmallow, still got all data & no bugs (yet)
