Due to a change at Sina Weibo server side on Sunday (Nov 11, 2012), log in to Sina Weibo from Facade on all new installations are broken.
We published a patched version at Google Play Store as of now. Please kindly update.
We are working to release patch version for Facade premium as well as Facade released in Amazon Appstore and Samsung AppStore, Blackberry AppWorld, However, the timing on those releases are largely subject to Amazon/Samsung/Blackberry's approval turnaround time.
Apologize for the inconvenience caused!
