Samisu, in desktop app i have closed shop (like on test server), in web browser its open, can you look into it?
The shop is available in the mobile app and in the browser versions, while Windows client should open it in a separate Browser window. You can make the purchase in browser version if the client doesn't open the store for you, for now, and our team will take a closer look into this.
Edit: Windows client version is now up to date, so the shop should work again.
