I’ve had a couple of reports stating that after their devices were upgraded to 10.2.1 software, that the sound alerts for Emergency Alert stop functioning after a small amount of time.
I’m currently investigating, and it seems like this should be fixed in the latest release (v2.0), which should be available soon.
Workaround
If you are currently experiencing this issue, please delete and re-install the application. So far everyone that has re-installed have reported success.
Unfortunately at this time there is no support for backing up rules, which means they will need to be recreated. Rule backup/restore will be available in v2.0.0.0.
