  1. Hi, I tried doing the other article you posted. I keep getting a “failure to connect” while using the app. I cant find a way to get rid of the bundle error. Do you know any other way of fixing this issue? Is there anything i can do in Filza?

  2. Hi, I had my device jailbroken and everything. Everything was running fine. Then one day i had to unjailbreak to use my bank app. After i rejailbroke my device (Iphone XS-ios:12.0) i keep getting the preference bundle error. I followed what you said exactly. Some tweaks work just fine like Barmoji. But BetterSettings isnt loading neither is Noctis12. Im not sure what to do. Ive tried rootfs and everything. Still nothing. Also the really weird part is the tweak itself is working 100%. Its just not loading in the settings. Is there something i can do in Filza maybe?
