Walkie Talkie not working on iPhone in background or when locked
I'm having an issue with Teams Walkie Talkie not working when the app is in the background or the phone is locked. This issue is occurring on an iPhone 11 Pro Max, iOS 16.2. I'm connected to a channel, and the app functions as expected when Teams is open on screen. However, when Teams is running in the background or the iPhone is locked, audio communications from other people/devices do not come through. Teams has full access to notifications, background app refresh, cellular data, etc. Volume settings are correct. No other walkie talkie apps are installed that may be conflicting. Other users continue to see this device as connected to the channel when it is locked or running in the background. I appreciate any thoughts or suggestions on this issue.
