Steam Login + Client Issues?

It seems like the newest Beta update for the Steam Client is causing an infinite loading screen. I was able to opt out of the beta and thus login to the client but now that I’m logged in and ‘Online’ I can’t access the Store or any of the online features in any games. So I guess that means I HAVE to use the beta version to get online access but then I’m unable to log into my account? Is anyone else having this issue?
