fedcram: Guys I solved the problem. GOG client didn't was able to recover my TW3 copy from my PlayStation library because I never ran the game. I only installed it, but the client, i think, search the information about the games with savedatas. So, the problem of the connection to PlayStation is not still solved without using the workaround, but as @lostars said it's very important ran the game!
I had same idea. But that didn't work. I have physical copy of GOTY version. Before running I have logged to psn store, have installed the game from dvd, updated, Restore licences, run the game, loaded my savefile. Having everything up, logged to gog galaxy on pc, added psn account, synchronized. Received my game list from psn. There are all my games digital and physical, but no The Witcher 3.
What I actually thinks is that they after making this promo, realized that everyone can just make as much accounts as he wants using ps4 and game disk. As you can create email, register psn account, install the game, claim on gog. And make it again and again using same game disk. I think just owners of digital copy can actually claim the game.
