Check your library in the app / if you can not see it close the app restart your pc try again it should show up in your library but falling that log out of the app and log back in good luck .
I have same issue, on gear vr. Bought in the store. Not showing up in the library as bought. Same message you already own the app (ok so let me download it then!)
I'm having the same issue. Bought a game, shows that I bought it in "recent purchases", but it's not showing up. When I try to buy it again, it says "you have already purchased this item" or whatever.
I am having the same problem. I bought SuperHot, but it's not showing up. I have restarted. I am up to date. I can see it in my purchased history, and it won't let me purchase it because it says I've already purchased it. I'm seeing this same complaint elsewhere on the web, what's going on?
