Cannot connect to server, the app doesn't works


I've a Samsung Galaxy S7 and when I try to open the app it always say:
"Server connection error. There is some problem with the Garmin Connect server. Retry"
The only option that I have is to click "Retry" and nothing happens.

I've set all the possible permissions to the app and two times tryied to uninstall and reinstall.

(I've a Garmin Forerunner 245, I know it is not for golf but I know there should be some options to use it for golf, or not ?)

Thank you for any suggestion
