I'm having an issue when running the process, it happens everytime I see the app start to download on my phone screen, then this pops up. "There was an issue during installation: 3892346881: ApplicationVerificationFailed (Failed to verify code signiture of /var/installd/libary/caches/com.apple.mobile.installd.staging/temp.arloti/extracted/payload/customstreetracer2.app/extentions/backgrounddownloadextention.appex :0xe8008001 (An unknown error has occurred.))"
