The feature for entering sleep manually is buggy. You have to click on done, for it to save the start or end time you set up. Typical iOS design language is that clicking anywhere higher than the Title (Starts or Ends) it should take over the time. It is not possible to set a start time earlier than 00:00. If I went to sleep earlier (e.g. at 10 in the evening, I still have to set 00:00). It is not possible to set an end time later than the current time, even when logging an entry for a different day than the current one. If I want to log the sleep from two days back at 6 in the morning, it doesn‘t allow me to set the end time from the day in question to 8 o‘ clock. I always have to navigate to the sleep section to log a manual entry. The feature should also be included in the new plus icon on the main screen.
