I have watched videos that show them somehow placing the portkey on the floor, but I can’t figure out how to place it myself, it just has a hand pointing up my screen with a blue line going across the screen. Please can someone help me?
Found it critical to keep the phone parallel to ground at about heart height when placing the boot, and keeping the phone parallel to the ground when stepping in to the portal.
Rebooting fixes my issues when the boot won’t place, or the boot is tiny (opens underground).
Darkness also seems to be a factor.
