> ...After that you should go by onEnterSleep and onExitSleep as they will tell you the state of low power on/off

Yes, the last of these functions to be called will tell you the state of the system. Most normal apps only care about the current state, so that is not a problem. In this case the issue that is being described is that onEnterSleep is being called by the system when the 10-15 second gesture timer expires (you lift your arm and look at the watch for 15 sec and it transitions back to low power mode) and then it is being called *again* when you put your arm down. That is a bug.

I had unintentionally posted a duplicate comment and then removed it. This is still being looked into. 

don't you think that teaching how to use forum in 2021 it's strange? Simple, forum after update is poor, I don't understand why it's not fix - Garmin looks unprofessional and why it doesn't fight for good product.

I probably hate this forum more than anyone else....

There's better options like NodeBB and Discourse, which solve issues this one has with mobile support and navigating long threads, but we're probably stuck with this one forever. You can't even properly quote text unless it's part of the current discussion, and quoting doesn't seem to work in the Bug Reports forum at all.

1. it doesn't run always! Now, I still can't see Richard's reply and didn't see your but was small "reply" which run

2. don't you think that teaching how to use forum in 2021 it's strange? Simple, forum after update is poor, I don't understand why it's not fix - Garmin looks unprofessional and why it doesn't fight for good product. But is not my matter, if Garmin like it, ok.

I cant' see Richard.ConnectIQ post so  I repeat it:
