Samsung Health v7 temporarily prevented workout and step data from writing to Android's Health Connect framework. Samsung has since released an update resolving this bug and restoring full syncing functionality to Lose It!.
How to Restore Syncing
Update Samsung Health: Update the Samsung Health app to the latest version in the Google Play Store or Galaxy Store.
Verify Permissions: Open Samsung Health → Settings → Health Connect and ensure permissions for Steps and Exercises are toggled ON.
If steps still do not sync: Go to Lose It! Profile → Automatic Tracking → Health Connect, then tap Disconnect and Reconnect.
