Microsoft today is releasing a new Windows 10 Mobile Build with version 15063.2. The new build is being released to the Fast Ring Insiders. The build is a Cumulative Update for Windows 10 Creators Update with a minor fix.
The company has fixed the issue were users on Anniversary Update were unable to download directly to the latest Creators Update Preview Build. With the latest Mobile Build the users on Anniversary update will now be able to download the latest Creators Update Build without any issues.

The latest Mobile Build is a further confirmation that 15063 is the Final RTM Windows 10 Creators update which the company is going to release to the General Public in April. The current Build is only available for Mobile Insiders in Fast Ring and we expect the same to be released for users on Slow and Release Preview Ring very soon.
The Latest Cumulative update is currently available for Fast Ring Mobile Insiders and you can download by going to Settings>Phone Update>Check for update.
