Update Sleep app missing morning hours on iPhone

why does the updated sleep app go from 00hrs to 35 hrs (i.e. no 07hrs-12hr)?

the morning hours are missing from both 24-hour clock as well as 12-hour clock.

Re-enable Sleep Schedule

The graph behaves correctly only when a Sleep Schedule is active.

  1. Settings → Focus → Sleep
  2. Tap Schedule
  3. Turn ON “Sleep Schedule”
  4. Set a bedtime and wake time (even if you don’t follow it exactly)

Then reopen the Health → Sleep graph.

This forces Apple’s sleep timeline back to 24-hour mode.
