Also please note that the developer console doesn’t execute progressive responses properly, so try it on a device

I'm using your code. I just changed the time.sleep(5) to time.sleep(10) and get "there was a problem with the requested skill's response"

I thought the whole point of progressive responses was to buy more time?

ah. it doesn't get you any more time :(

"Note: Progressive responses do not change the overall time allowed for a response. When a user invokes a skill, the skill has approximately 8 seconds to return a full response. The skill must finish processing any progressive responses as well as the full response within this time."

progressive responses are so there's not a 8 seconds of silence.
