Control Center option in settings is grayed out on my iPhone
My iPhone is on IOS 17.7 and just a few days ago I noticed that I could no longer swipe down from the upper right corner of the lock screen to adjust brightness, volume, calculator, etc. Nothing happens when I swipe down. I have not upgraded recently and made no other changes to my phone in weeks.
I did research and found that you go to Settings, then Face ID and Passcode, scroll down to Allow Access When Locked and see if Control Center is toggled On. Both it and the Notification Center options are grayed out, I can't even toggle them on or off. Other options I can toggle.
I did more research, found I should check Screentime, Content & Privacy Restrictions (I am adult and have even needed to go to this part of settings). It's not enabled and every option is set to Allow.
What else is going on? I've done a hard reboot several times. I don't really want to upgrade IOS just to fix this - what changed from a few days ago anyway?
