When I try to add sleep manually, the app only allows me to set the start time from today at 00:00. This means that if I went to sleep earlier, for example at 9:00 PM, I can’t add it. Additionally, I often have problems when I forget to wear my Watch or put it on later. If I try to add a sleep period manually to cover the missing data, the app does not let me. Sometimes, I add the sleep period, but it disappears right after. I have also tried modifying my sleep data directly from the Apple Health app, but the changes do not appear or update in Bevel.
