Hi. I've just installed SmartTalk on my Nexus 4 and it's great - except it only lets me make one call. After that, it becomes "not ready". When I try to use it a second time, it says there is a problem with my connection and invites me to run a connection test, which then hangs forever with the progress wheel spinning. I have to kill the app and restart it, after which I can again make one call!
There is nothing wrong with my connection, BTW - I'm on a spanking new office WiFi system.
