i have the iphone XR and just an hour ago, when i would turn my phone off the home bar on the bottom of my screen wont show up so i cant open my phone. it will scare my face id and say it’s unlocked but i cannot swipe to open my phone. i use the control center and open calculator so i can still get into my phone and when i do my home bar is back. i’m not sure what i should do in order to get it back on the lock screen.
