Apparently there is one SharePoint App for Windows 10 Mobile...strange thing is (and I wonder why) that it's only supported for Windows 10 Mobile and it's not supported for Windows 10 Desktop
Actually it is available as a universal app on Windows 10, as I have it ;) Strangely though only the mobile app was updated with News. @Loryan Strant, this is indeed the full News capability as in iOS etc not just the newsfeed.
I think it could be just a question of your location...If I look for the app in the store I only see the mobile one and it seems I cannot get the App for installing on my laptop
OK, Microsoft must have changed something. On a PC where I had never installed the app it no longer appears in My Library. I definitely have it installed on my Surface device though!
