This is not regarding the new kitkat hangout with SMS integration. I've been trying to use the hangout app, but whenever I select a contact, it tells me the person is not yet on hangout and asks me to send them an SMS invite.
I know for a fact these people are on hangout, and when they try to start a conversation with me from their phone they get the same message, even though they do not expericne that problem with other people.
A Google search and a search of this forum got me nowhere. Any ideas?
