I enjoy the app, and im really glad they gave people options for this, just to be more flexible. Ive only had it for a short time and noticed some problems though, at least on my phone. When i use push-to-talk, it is extremely delayed so i have to hold the button for several seconds before it begins to transmit. The biggest problem though is that once im talking/the push to talk button is working, everyone elses voices shut off even if they are still talking. Not cool at all, completely ruins the conversation. Fix that and Id be satisfied :)
