0.11.3 + 0.9.29 - wear time will randomly halt in spite of syncing being up to date and band has not left arm #450

Open

Description

@cb0806151

What happened?

Randomly over the past few days, wear time will just halt all of the sudden (even though the band is still on my arm, live bpm is still coming through, and syncing is up to date.) This will in turn halt the breakdown of the day for the rest of the day.

Expected: wear time continues since band is still on arm, live bpm is coming through, and syncing is up to date.

Steps to reproduce

  1. Wear band for a while
  2. Notice some days experience wear time halting

App version

0.9.29

Platform

Android (APK)

Phone model and OS version

Moto G power 2022 - Android version: 12 S3RQS32.20-42-10-9-12

    I'm not sure if it ties into this but I noticed some 'data decay' when going back through breakdowns; in this example it recorded sleep data starting at 11:58 PM but in the breakdown we see it only starting much later in the morning

    This is not reflected in the sleep data, just the breakdown:

    These occur fairly regularly starting less than a week earlier than the current day

    This issue is still present in 0.11.3, seams like if the data processing hasn't finished by midnight then it just cancels it and starts processing the next days data:
