I want to report this odd bug. In my response, I set shouldEndSession to False, but if Alexa says nothing, it ends the session immediately regardless of shouldEndSession.
I am looking to call repeated actions in a short time frame, like saying move down, up, up, left, etc. I don't want Alexa to respond to each action, but just listen quietly for more instructions until the session times out.
To workaround this issue, I set Alexa's response to " " (empty space). This allows Alexa to keep listening between actions even if she doesn't actually say anything. This is the behavior I originally expected.
