No notification sound and Siri muted after installing iOS9
Hi,
I upgraded my iPhone 6 / 64GB from iOS 8 to iOS9 today and the Siri is muted. I able to use Siri features but there is no sound (she doesn't speak at all). Same thing happens on notification sound. Sometime I get notification sound 'Beep' on WhatsApp new message sometimes don't.
is this a bug?
Regards,
Leandro
