Thanks @jrgm, but I am a bit confused by this. What we are seeing seems to be the opposite. If you log in again within the 60 second timeframe, you do not see the challenge screen. If we set a delay in the test so that the second log in is more than 60 seconds after the first, then we do see the challenge. Does that make sense? Am I misunderstanding what you are saying, or are we seeing unexpected behaviour?
