For some reason, and I think it has been like this has been like this since I bought the G3 in September,
The facebook notification volume is not controlled by the notifications volume bar, but the ringer volume bar.
This is very annowing as I keep my ringer at a maximum volume and my notifications at medium volume, but the facebook notifications keep sounding really loud. Then I have to lower my ringer sound, but then my phone ringer is lower than I want as well.

Does anyone know of how I can get the facebook notification volume be controlled by the notifications navigation bar?
By the way, Im still using stock KitKat. Did not connect with the lollipop rom when it first came out.

Thanks,
