Whenever I have the unc0ver jailbreak downloaded it never lets me download any apps on the App Store with Face ID. Help

Hello,

IPhone: XS MAX
Version: 12.4
Jailbreak: unc0ver


I'm having an annoying issue at the moment with my phone not showing the tweaks on my home screen. When I jailbroke my phone, I went to install Anemone first and it installed and springed successfully, but the icon did not appear on the homescreen, nor in settings. So, I'm thinking "how do I use the tweak if I can't access it since it's not showing up". And, I thought maybe it was that tweak and it needed to be updated, I don't know. So, I went to go install another one called Asteroid, and the same issue happend. It does not show up on the home screen and I cannot access it. Although, I just installed AppList and RocketBootstrap, and has soon as I re-sprunged, I was brought with a setup screen for Asteroid. And, so I'm thinking "Yay! It works, let me set this up and I'll see the icon on my home screen now" but nope...still nothing. I'm a noob to all this and I apologize if I'm over-exaggerating something that is super easy to fix lol. 

What i have installed:

RocketBootstrap
AppList
PreferenceLoader

I saw Geo recommend someone to install Cephei but It doesn't show up in the search results.


*UPDATE*

Just found out how to get Cephei, I went to packix repo and installed it from there. Now, I installed Anemone and the icon appeared! Now, I'm doing a hard reset and going to re-jailbreak, then going to re-install Asteroid to see if that icon appears.


*UPDATE 2*

Asteroid tweak icon still doesn't appear, I uninstalled Anemone due to some error I was getting. I went to go install snowboard, and it installed successfully. It showed snow fall but still no icon on the homescreen nor in settings. I have no clue what to do...



*UPDATE 3* 

I had to upgrade PreferenceLoader and the tweaks finally showed up in settings! I'm not sure if they are only for settings and not shown on the homescreen but I'm glad its working now!

Whenever I install a tweak in the settings it says "There was an error loading the preference loader for [Tweakname]"

i have a problem  
iphone xs max 12.4 after jailbreak face id stop work in some apps 
any fix for that

Open cydia, click on the sources tab and add https://rpetri.ch/repo/ and respring your phone. It should work out temporarily until the developers actually start pushing updates for their tweaks

i still have a problem even after downloading ryans repos and re jailbreaking. re installing and updating preferenceloader and rocketbootstrap. only tweak i got to work was barmoji all the others don’t seem to open up in settings but are there

Who can help me please? My iphone is dead when i connect on itunes i got error (0xE8000065)

For all of my tweaks, i get "There was an error loading the preference bundle for (tweak name)

Spotify keeps freezing whenever i try to play a song or press pause/play (In the app or in Control Center). Libertas, Liberty, No Sub, and WorkFFS dont seem to stop this from happening. Any guidance, input in resolving this would be greatly appreciated
