Garmin Instinct 2 solar backlight not working

Hi,

I'm using Garmin instinct 2 Solar and I noticed that watch backlight is not working. All the parameters are turned on (keys, gesture, alerts), backlight is set to 100%, power saving is turned off. I have tried to restart it but it did not helped. Can this be because of recent software update to version 8.10? Does someone had a similar issues and have a fix for this?
