I'm using sinch and I've gotten the client to work by registering a user, but I can't send a message. When I click my send button, nothing happens. The required methods that need to be implemented, such as messageFailed(), messageDelivered(), etc. are not being called either. Does anyone know why?
Have you registered the one more user? Can you enable logging and share the full log output.
See comment below, user tried to send message to self
