Did not hear the alert.
Just had a severe thunderstorm hit my town. Did not know I was under a severe thunderstorm warning until it actually hit and I pulled my phone out to look at the radar. The my warn app had a notification on my phone screen but I never heard the alarm. The alarm needs to be loud and it needs to sound until disabled. The geo terrestrial app ( no longer available) would do just that and you could even set different alarms for different warnings.
