The app has come a long way in improvement since I first installed it. Calls are crystal clear now. The only issue now is since the last update, whenever I answer a call, it automatically goes to speaker. There is no way to change that feature and it's a hassle to try and turn it off before everyone else hears who is calling you. Turning on "Audio Only Calls" doesn't change it back. Tried that. It's not a video issue. It's the speakerphone being the default setting that's the problem.
