It keeps randomly but regularly loosing connection and reverting to the friends select screen.

Not just for me but my pal too.
Anybody else having problems?
We already tried purging the chat history, also both of us connect from Germany.

It´s a new problem, never had any issues with it till now.

I assume you're using Galaxy?
Sounds like a bug. I'd contact support.

A bug with two different clients?
Sounds wierd.

Really nobody else out there with these problems?

I have this issue as well.

Well at least it seems to be a client problem then.
Was suspecting some german internet routing issue at first.
