I play only team fight tactics, and I reached platinum rank past season. Now when set 2 arrived during game loading my profile don't have ranked border. It shows only my LOL honor border. The other players have their ranked borders on point. I didn't change border which I want to see in my profile setup. I can see there my platinum rank, and that I have chosen ranking loading border.
Sometimes you may be waiting few days/weeks after the end of the ranked season as G.Eiwell said. Moreover the season 9 ends 19th November. You will not receive Aatroxx victorious skin for being at least gold in TFT.
