In your device’s iOS Settings app, make sure that alerts are turned on
for Storm Shield (Settings > Notification Center > Storm Shield
> “Banners” or “Alerts” are selected; “Badge App Icon” is enabled;
“Sounds” are enabled; “Show in Notification Center” is enabled; “Show on
Lock Screen” is enabled; also, make sure Storm Shield is listed under
the “Include” section in “Notification Center”). If alerts still aren’t
being received, you may need to delete and re-install Storm Shield. You
will NOT be charged by Apple to re-install the app so long as you use
the same Apple ID you used when you purchased the app.
