Arlo Pro Siren Button Missing In App

[rodzulu]

Have lost ability to arm siren ( turn siren on ) in mode setting 

Now have to delete Arlo, then add device to arm siren 

the only option in the Arlo siren box in mode is do nothing

I just tried it using the Android app and it works as expected. Try restarting the base as well as reboot the phone and reinstall the app.

rodzulu,

Have you tried using the Web Client to see if the alarm setting is there?
