If the phone reboots and alarm is not correctly snoozed, it should continue active after restart. I’m a heavy sleeper and the sleepy me learned to reboot phone holding power button for 9s…

Copied from original feature request:

In a similar scenario, I discovered this morning that my phone had done a software update and rebooted last night mid-sleep tracking.

The app didn’t restart the tracking after reboot, and the alarm was cancelled apparently.
