Omnipod Dash pod alarms

I’ve noticed that the new Omnipod Dash pods seem to alarm differently than the old version.
Usually when I have a failure, the pod will alarm and is shut down and stopped by the PDM. I’ve had 2 Dash pods recently (just got started on the system in Nov 2019) that kept alarming even after they were disconnected by the PDM. It was pretty annoying the first time because I was in a crowded area with no way to stop the alarm except by smashing it on the floor!
Just curious if anyone else has had this experience.
