I just reinstalled my Surface Pro 4 and can't find or install the Surface App for the pen. I got the i7 512 gb ssd and wanted to partition it, so therefore did a clean install of Windows 10. According to Microsoft I should just have to search for the app in the store, but it can't be found. I was able to get a link to the Surface hub app but when opening it I just get "surface is currently not available" (New Official "SURFACE HUB" App in the Windows Store! | Microsoft Surface Forums). Anyone having any idea what that could be?
