Used aqua aerobics to track water exercise. Water lock turned on when started. Seemed to work correctly and track results. When completed I tried to turn off water lock so I could end the exercise. Played sound as normal but would not exit water lock. Subsequent attempts to exit just got error saying can't play sound while another sound is playing. Since everything is frozen in water lock mode, had to force reboot the watch which cleared everything. Exercise was saved and synced after the reboot.
Did successfully send error report before restart.
