Yes. If I follow that link I'm directed to Affinity Photo in Mac App Store. The reason why I wrote my post is that I couldn't find the app 'by searching' or 'Purchase list'. I was quite confused why I can't find the app on there although I already bought it. At the end I found the app by myself through 'Category' menu, and was able to download it without additional payment. (Of course it should be!) I installed Affinity Photo without any problems. (Actually I tried to install it from my Apple Time Machine, because I backed up before re-install the OS X, but I cared about further updates..)

Hi. I purchased the app on Jul. 15th 2015. As I re-installed OS X, I tried to download the Affinity Photo through the App Store. However I couldn't find the app on the purchase list. So I tried to search the app, but not shown! (I'm using South Korea App Store.) As I have US Apple ID, so I tried to search with it, and I could see the app. (on US App Store.) But with Korean ID, I couldn't search it. (Not shown on the result.) However, I just found the app, by surfing 'Categories' menu, Photo section. It was so ridiculous that the app is on the App Store but can't be seen by searching. I asked this to apple support but the advisor said it's because app developer changed something. Such as, replacing the old one to newer or something which I can't understand. So I'm asking that PLEASE make the app can be searched on Korean App Store. * The first screenshot is the searching result, and the other one is app category.
