My sleep tracking does not sync to my phone. I cannot see sleep tracking details.
On the watch, I see the hours and minutes with a message, "Show on Phone."
When I tap on Show on the phone, the message is "couldn't open app on phone." This is an important feature for me.
Do I need to purchase a Garmin?
Do you have a Samsung Galaxy Phone with Samsung Health App?
I think that you need the Samsung Health App on your phone and that is available only on Samsung Galaxy phones.
