Mike's iPhone 6 plus isn't accessing his WiFi. It gets bumped off. Leo says that sometimes Apple products can be a bit promiscuous with WiFi because it's always looking for a stronger signal. But it could be the settings in another device that has WiFi access that's luring your device away.
Mike also can't seem to follow Leo on Facebook. Leo says that he has a private facebook page and a public facebook page. And his private page isn't taking followers because it's ... well private. But Mike should be able to follow Leo's public Facebook account.
