Describe the issue

Signing the latest version of watusi fails, even after:

relaunching LC
updating LC (latest from the actions tab)
reinstalling sidestore, regenerating certificate and reimporting it into LC
trying like 10 times with slightly different settings

The issue occurred after updating watusi from a previous version to the latest one. I am not 100% sure whether this is a watusi or a LC issue.
However, as installing the IPA usually outside of LC works, I believe it is.

please see here for a video demonstration: https://streamable.com/vtuvvc
or https://web.archive.org/web/20251101164135/https://streamable.com/vtuvvc

(file size too large for github, but I can reupload the video if needed)

Instructions to reproduce

download and install sidestore, then LC
download the watusi ipa given below
attempt to install it in LC

at this point, signing will fail.

What version of LiveContainer and iOS are you using?

3.6.56-Release, iOS 18.6.2

Verify steps

I downloaded LiveContainer from releases / actions section or LiveContainer's AltStore source.
I have the latest LiveContainer.
I installed LiveContainer through AltStore/SideStore/TrollStore or I'm confident that I signed LiveContainer correctly with all required entitlements.
I have tried to sideload the app normally through free sideloaders and I did not encounter the same problem

The name, version the app having issues

WhatsApp Watusi from https://github.com/FouadRaheb/Watusi-for-WhatsApp

workaround (pre iOS 26.0):

enable "don‘t sign new apps" (necessary)
install watusi, receive the error message, ignore it
enable JIT for watusi
launch watusi with JIT
