I'm on a 9700 running 5.0.0.423
Did the OTA install, ran VersaTool, and allowed all the permissions it asked for. I added an HSB to launch Bolt to see how the feature works. It appears to have added it, and it's in the list, but nothing appears on my home screen. I have also tried to reinstall the launchers, which said it would ask for a reboot, but never did. Finally, attempting to delete the HSB results "Error deleting Bookmark: java.lang.IllegalArgumentException".
I will continue to play.
