Won’t work pls help – Hearthstone Review

Been playing for 7 years and I got a new iPhone and when I download the game and get to the main menu I have no sign in option. Nothing on the gear icon once I click or anything. I’ve tried different Wi-Fi’s and my 5G Verizon data. Nothing. Can anyone help? I cannot log in it only lets me sign up…..
