Someone also has this problem ? My phone has already been restarted and the app reinstalled but it still happens ... Can no longer send Workouts to the watch because off that.
I too am having the exact same issue where I open the Garmin Connect calendar and it crashes to the Springboard on my iPhone6. It seems this is a relatively recent occurrence.
Fenix 5, iPhone 7 plus (iOS 11.4), Garmin Connect App for iOS(v: 4.7.0.14) - I've got workouts I've made on the connect website that will upload to the phone and to the watch - but selecting the calendar at the bottom of the screen results in the app crashing. Been happening to a workout buddy as well using an iPhone 5 doing similar workout entry. I've restarted everything, reinstalled the app, etc.
Running an iPhone SE updated today to iOS 11.4. FR230 running ver 7.70. Connect Mobile app very 4.7.0.14. I noticed this same issue two days ago. Every time I try to go from the mobile app home screen to calendar using the icon along the bottom of the screen, the app crashes.
My wife's FR25 does not do this. I have to believe it only impacts those of us who have workouts placed on our calendars.
Same problem I have got since June. Crash when click calendar and can’t sync the work-out to my watch. I am using iPhone X. Same problem happened when I use back my iPhone 6. But my friend who using Android has no problem at all.
