When the alarm goes off then the dismiss and snooze buttons are missing. The only way to cancel alarm is to either restart watch or go to actual alarm app and toggle off the alarm. Even trying to go into the app menu and selecting the alarm app is hit or miss because after pressing a series of buttons while the alarm is going will render the watch screen completely blank and all buttons won't do anything (except to restart the watch). At that point, I either need to restart watch by pressing the A button for 15 seconds or just wait for the alarm to stop after 1 minute then the watch returns to normal.
