Can not seem to talk through app. When I tap the microphone I get a connection failed error message
Does the app have microphone permission on your phone? Check in your iOS settings for the Wyze app.
If that is fine, maybe try rebooting the cam and maybe even your phone. If none of that works it may be some sort of connectivity issue, something getting blocked, or maybe wifi signal can only handle the video and doesn’t have enough for 2-way audio too.
