With fw 12.27 I put the watch in "night mode" (the quarter moon symbol) and I had dimmed screen and no notification, useful for going to sleep.
Now with 13.22 the sleep mode only acts on screen brightness and watchface, to have no notification I have to also activate "do not disturb".
Yes, I know that I can auto activate it in sleep mode, but my sleep time it's not always the same, I've set it from 23:50 to 5:40 because these are my times during work days, but on sunday I sleep till 8 and with do not disturb only during sleep time I will recive notifications since 5:40.
So, now I have to do 2 operations before and after sleep instead of 1, activate sleep mode to have dimmed screen and do not disturb to not have notification untill my REAL wake up.
Garmin, you think this is smart?!
