From OP if you missed it: Known issues for Mobile Updating from the Windows 10 Anniversary Update (Build 14393) directly to this build won’t work. There will be an extra hop required to get to this build. If you use WDRT to go re-flash your device and join the Fast ring, you will not be offered this build and instead offered Build 15055. Once you’re on Build 15055, your device will find Build 15063 and take the update then. Some users are reporting that pages are constantly reloading or refreshing, especially while they are in the middle of scrolling them in Microsoft Edge. We’re investigating.
If it's not final, i will simply delete the word "Final", for now MSFT is not clear about the state of this build!!! If it's not final build, my wife is going to kill me in about 1hr
The 14393 to 15063 Upgrade is NOT yet Live. It goes Live tomorrow. Also .ESD's released tomorrow. We got build early before everything is ready.
