Sleep tracking and nap recognition gone worse with Beta 12.x

In the past nap recognition and sleep tracking worked fine. When staying awake in the night, the watch maybe recognized a sleep block before the awake phase and a nap afterward.

Now, it seems like beta 12.x or maybe the later 11.x version I'm facing the issue:

  • only one block of sleep is being recognized
  • no nap is being recognized, neither in the night after an awake phase nor during daytime. This is not only valid for short nap, also a nap > 1h is not recorded
