So I'm curious my gf doesn't have the messenger app just the fb app. It'll show her last active time. The past two days late at night she got on and it was saying active 1m ago but it stayed that way for 17 and 11 minutes. Then when she wasn't using it, it accurately stated active 2m,5m ago etc. So when it was saying active 1m ago for a long period of time is that just her scrolling through the app, her talking to someone or a mixture of both?
