Usually my Venu2 is always connected to my GC android all day and night. Without fancy notifications I like the battery life 7+ days.
But I am biking with the Edge1030 several times a week + wearing the Wahoo HR strap, and when I got home the Edge auto sync in my garage through a wifi.
When a sync is done, I am looking at the connected devices in GC and the watch is disconnected. No other way around I need to shot down the watch and restart = I tried to restart my Samsung S20 phone but that does not have any effect, only a Venue2 restart (with a shot down + start up again) will do a change.
After this exercise the Venu2 works just fine as usual days.
Also to add, when I wake the Edge 1030 from a sleep with a button, that connects to a phone + GC automatically, I don't need to worry about that -for now.
I cannot recall changing things in settings in any units, the only suspect may be some Garmin updates in a past 1-2 months?
Any tricks I shall try?
