No audible notifications for text messages on iOS10.

iMore Question

Since installing iOS10 I have not been receiving audible notifications for my texts if the phone was in sleep mode/screen off. If I was using the phone then it was working fine, however as soon as I turn off the screen I do not receive audible text notifications.
After some research online I came across a post about Bluetooth issue that sounded similar to my issue. Just for giggles I turned off my Bluetooth and BAM all is good. Has anyone else come across this issue and if so or even if not how do I go about notifying Apple???
