No, you can add 15+ by adding 1 by one in the player profile. Are 2 different spaces, the 25 from regular video/boosters screen, and then, for example, go training and select add booster to recovery a player there, inside a player profile - watch video. It will show up available inside the player profile, until 15 more videos.
What are you up to there? lol Somehow the videos have been opened miraculously and I could have indeed watched at least 6 more. Bizarre, the miraculous account issue solver: Khris Payet. He is the hero of us!
