What exactly do I need to turn off on my iPhone for this app to let me sign in??? – Halo Waypoint Review

Turned off every pop-up and cookie blocker on my phone and the app still won’t even let me sign in at all. Very disappointing and non-tech savvy. Best to sign in from the web browser on one of those old fashion computers until this issue gets fixed indefinitely.
