Edge 130 reboot instead auto-power off while ride active

Have next issue:

Pre-conditions:

  • auto power-off enabled
  • ride active, but paused
  • connected speed sensor (v2), cadence sensor (v2), heartrate sensor hrm3-ss. all sensors connected via ant+
  • without speed cadence sensors - same behavior, described below

Issue: when ride auto paused, or temporary stopped with Start key and no activities for 20 minutes Edge ask for power off. I confirm, but device restarted and back to ride.

No difference with confirm power off, or Egde power off by timeout

With connected iPhone via Bluetooth issue reproduce often. 

Affected Firmwares: 3.40, 3.50.
