My so far short experience with the new beta has yielded two observations:
a) The PayPal page won't come up. It says I have no connection to the internet. Sometimes it says this right after I choose the 'Send money' option on the menu, sometimes there is a wait with the Skype yellow lock showing, and then the no connection message shows.
I can access my account details from within the client just fine though.
b) Help and tips keep showing, even though the relevant tick-boxes are unticked in the options.
