See attached image, why is it not showing the remaining time on the timer on lock screen? Just 0:00 always!
Ps the timer has not ran out, it's always 00:00 even when I just set it
My girlfriend has had this issue since 7.0
If she uses a 24 clock then it works fine.
Try that.
Been a bug for her across 2 iPhones.
You could restore your phone to new see if the issue is gone then try restoring from a backup. If it comes back after you restore it's an issue with the backup and you could fix it by setting the device up as new
