My iphone freezes during the night, having the alarm not go off, me miss important things as I oversleep. And the phone needs to go thru hard reboot to get back to normal.
It´s only been happening after I started using "Downtime". (An underdeveloped feature by Apple in the first place). I love locking my apps down nighttime for less screentime.
Annoyingly it only happens once in a while, so I´m not able to link it directly to downtime consistently.
I´m not developing an app right now so I´m steep ground with this post, but, with lack of sleep as this has messed up my sleep rythm several times, well I´m not able too anyway.
I know ios well, and there isn´t much "to do" except having to always remember to turn off downtime (it doesn´t play well with shortcuts app either), but I hope someone from apple sees this and is able to push this bug into the right team as all reports I have seen goes on focus modes bugs, but not "downtime".
