Hi @Lorraine. On Sunday early morning the sensor about to expire alarm came on and that is LOUD, both vibrating and fire alarm bells. This bypasses the Do Not Disturb.
The other night at 3am my phone vibrated and beeped b/c it need a calibration, again bypassing the Do Not Disturb of my iPhone.
Also, even when you have the HIGH and LOW alarms set to vibrate, the phone still vibrates when you have the watch on. Why did they change this? Vibrate is just as loud when the phone sits on your desk.
