The pretty little chime when motion is detected is gone. Now it has the same ringtone as all the other app notices. I see no way to select a ringtone on the latest version. Bring back tone selection please.
You can download notification ringtones for your device at some free and reputable ringtone providers such as Zedge, Ring320kbs.com.
I think, restore to default and update again will be a better option.
