Pangu just pushed an update for the 9.0.x untether jailbreak version 1.2 via Cydia on Saurik’s repo. Here’s the change log:
Version 1.2 of this package removes the software update daemon, which protects your jailbreak and actually fixes a problem where Manage Storage world for unknown reasons show a spinny and never finish.
However, there is no any update to the iOS 9 jailbreak tool itself. So head over to Cydia now and refresh to get this update now. You will be required to reboot the device after installing the update.
Edit: Pangu released version 1.2 of its jailbreak tool for Windows. Change Log is as below:
1. Bundle latest Cydia with new Patcyh which fixed failure to open url scheme in MobileSafari
2. Fixed the bug that “preferences -> Storage&iCloud Usage -> Manage Storage” keeps spinning
