I would have posted this in the LibrarianSync thread but it seems to be
closed.
I have a Kindle PaperWhite 3 which I managed to successfully jailbreak. I have a few KUAL extensions running well alongside MR Installer and also have the ScreenShots hack working perfectly.
After I jailbroke I was under the impression the jb would stay even if updated. I manually updated to latest OS from Amazon

and I guess the Collection Management tweak isn't working on it.
If anyone can assist it would be nice. I use Calibre and have the
Kindle Collections plugin installed. I believe it's working fine and I've set it up properly. The issue is coming from LibrarianSync menus in KUAL. They say they updated the collections database but I dont see any updates. I have tried almost all kind of troubleshooting and have searched endlessly before making an account to post this for help.
Any insight will be helpful
Ps. Python and everything works fine, or else the ScreenSavers hack wouldnt work.
