Hi, Since yesterday, any Collaborate project I open in Unity 5.5.0f3 will freeze it. Unity becomes irresponsive for a few seconds, "listens" for a brief moment then freezes again. It's useless! If I turn off my network connection, open Unity and choose to work offline, I can work on the projects. But as soon as I turn it on and sign in, it starts freezing again. If I turn off internet, all good again. So, I can only work offline! Any clues? I'm on mac OS X 10.11.6.
