Screen lock not working with extended tracking

Hi guys,

the screen lock is not working after the inReach goes to sleep in an extended tracking mode. When I turn on the screen lock then right after that keys are locked. When the device is then sleeping and I press any side button, nothing happens. That is OK. But when I press the power button the device wakes up and the screen is not locked. What can be the problem?

Thanks for any advice.

David
