I see. I guess I was mistaken. Thank you for your advice. I will do my best.

thank you for your advice. I made alter account and I never play network speedruns but I cannot access activity cards. activity cards are only in game help card. In game help card i can use only ten last activity cards so after I finished second stage, there is not third stage's card in game help. This alter account does not join PS plus, but the other does. Do you have some ideas about this problem? Perheps PS plus does something bad? I'm sorry for using your time, and thank you for your kindness. I am not good at English so please forgive my childish language.

Thank you for telling me about rules. I have a question. So does the regulation allow to use activity cards in control center? Even if it's right, I cannot use it because in my ps5 there is not activity cards in control center. (It is why I used main menu.) Does it means my ps5 has some problem? Or this situation is same for everyone?
