A lot of Windows Insiders (on the Fast Ring) are not able to access the Windows Store. The bug has nothing to with app update or download issue as it appears to be a server-side problem affecting both Windows 10 Mobile and PC users.
When you will open the Windows Store, you will receive an error “Something bad happened, unknown layout specified in manifest”, the error is written in yellow colour. The Windows Store is completely broken and restarting the device won’t help.
Microsoft is however already aware of the issue and it is being actively investigated. Microsoft’s Dona Sarkar was able to find a solution that is to reset Windows Store and it should work fine. However, Windows 10 Mobile users cannot reset any app and as a result, you cannot browse the Windows Store on your Windows Phone until Microsoft rolls out the fix.
As Microsoft is already aware of the bug, the fix is expected to be released in the coming hours. Is Windows Store working on your Windows Phone or PC? Let us know in the comments below.
