My wife has a Fenix 5s Plus and she keeps losing her card information from Garmin Pay. We set it up and after a little while her card details disappear from the app and watch. We have set it up 3 times now and it issue keeps recurring. I have a 5 Plus, and have had no issues with mine after I set it up. We have the same iphone with IOS 14 software. My Garmin pay works fine on the 5 Plus but my wife's 5s Plus and app keeps losing her details
