After connecting the watch with the CMF Watch app and wearing the watch, go to the workout page in the app and start any workout. The watch will display the corresponding workout mode and begin the workout directly.
During synchronized workouts, if the app and watch disconnect, both the app and watch will separately record the workout for up to 5 minutes. If the connection is not restored within 5 minutes, the workout will automatically end on both the app and the watch. If the connection is restored within 5 minutes, the data will synchronize with the watch's workout data, but the disconnection may result in the app missing some heart rate data.
