No off switch. I work in remote areas with little or no data/wifi. As signal comes and goes, my phone connects/ disconnects constantly. I can't find a way to make this stop, so I either uninstall the app or have to deal with constant notifications of connection. Also, I was to be able to access all of my texts through my laptop, not just the recent ones... I can only get the newest texts... can't I access the archive??? I guess it's a good thing I don't use this app much. Its annoying as f.
