The wait continues for Windows Insider members who want to download a new build of Windows 10 Mobile, and it looks like we will have to wait just a bit longer as Microsoft continues to test new versions of the OS.
In response to a fan asking if a new build would be released today, and if it would be build 10575, Windows Insider leader Gabriel Aul stated:
"We are looking to flight a newer build than 10575 for Mobile, but will need another day or two."
You may be aware that the last two Windows 10 Mobile builds that were released, including the current 10572 build, required that Insiders downgrade their phones to Windows Phone 8.1 before installing the new build. Microsoft has previously promised the next build would allow for direct updates from older Windows 10 Mobile preview versions.
