The apps on Apple Watch already abended when saving
Before upgrading to MapMyFitness, the apps worked properly on both iPhone and Apple Watch, however once the old apps retired and we were forced to use this new MapMyFitness, the apps on Apple Watch is very unstable. It happened many times that the apps will be abended after a workout is finished, the result is the workout record and route cannot be saved and synced, and finally the whole thing is lost. Very disappointed and hope the development team can fix it on Apple Watch ASAP.
