onExitSleep after gesture on Vivoactive 4 not working

Hi, 

I am working on watchface, with some functions activated by wrist gesture. Garmin watches, when presenting any watchface, are usually in sleep mode and when user makes wrist gesture watch is exiting sleep mode ( onExitSleep method is called) and stays in this mode for about 10 sec. (then onEnterSleep method is called).

It works well for almost all devices beside Vivoactive 4 - users are describing that the backlight  is activated, but watchface stays in sleep mode.

Aby ideas how to resolve it ?

Regards,

Karol
