I have a Garmin Venu and always had to edit the sleep times in the app since it believes I'm sleeping when I'm in bed reading.
I usually click on the go to sleep time and edit it and press ok, and then press the awake time, change it, then ok, and then save. But then something changed in the app a couple of weeks ago. When I'm finished with sleep time and awake time and press ok, then the sleep time changes back to what it originally thought it was, and then I have to go back in to sleep time and change it again. This is new and haven't happened in the previous years I've used the watch. Is this something that will be fixed soon?
