I'm having a problem that the lockscreen clock, widgets and swipe to camera disappear completely.
A reboot will fix it but it's really anoying.
It's been there since ios 11 beta 2 en now on official 11.0.3 it's still there.
Noticed sometimes when receiving a notification the clock and widgets disappear from the lockscreen and swiping to open the camera isn’t working after that.
Yes I have a passcode and its set to immediately.
Just reinstalled whatsapp and it looks like that fixed it.
But i’ve sent feedback to Apple just in case.
