GRRRRRR just got my Surface Pro 3 and this is bugging the hell out of me. I can't install any app I have previously installed on any other device. Even free apps like Sway. Any app that shows I own it, and can install it, will not install. I can install NEW apps. And some paid apps I seem to have been able to install (Tweetium) I have tried every approach I have found, including those below. Please. There MUST be a way around this.
