People still won't update and as for Weather goes, every single page (except maps) shows the same error. This has nothing to do with Internet connection.
Seriously, mine updated. Try to re-install them from Store not Store(beta) under Account - All apps. Don't forget to unpin them from the Start first. You can as well run this at elevated command prompt to see if it helped: Code: Get-AppxPackage | % { Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppxManifest.xml" -verbose }
