Licenses Issue
I bought my PS4 back in December, and it included a code to download Battlefront. I downloaded it, and now have over 50 hours of gameplay. Yesterday I wanted to play, but it appeared blocked. It said that I didn´t have the license for the game (which I obviously have). I don´t understand why this happened and am really disappointed at this. I was even considering buying the season pass, but now I´m afraid you are going to take it away from me as you did with the game. I hope you can solve this because I really enjoyed the game but can´t play anymore.
To hazard a guess, it sounds like the game might have been consumed on your brother's account all along, but you were able to play it via the console's game sharing. If 2 people use the same console regularly then this could happen for a long time before it becomes noticeable.
