Sure,
I test mods on two devices. An IP8+ and an IPXS both running u0 on 12.4.
The IP8+ works just fine. The IPXS crashes immediately before any pop-up to log in or before the games title screen. When you open app switcher, it shows the "this game is not authorized on this device" message which is the JB detection trip but I'm unsure Hy the game crashes. As it doesn't do that and just shows the message without the mod installed, I'm to assume the mod causes the crash.
I have tried a number of solutions to troubleshoot before reporting back on this post. Here are some of the things I have tried:
Reinstalling
Icleaner pro cleaning
Along with liberty lite beta
Along tweakconfiguration
Along with shadow
Just the hack by itself
Rejailbreaking
It does not appear that it is working on A12 devices due to the game detecting the JB somehow still but I can not pinpoint why specifically.
