Hey, FYI, the app-release.apk is signed with a certificate that identifies as SideQuest, but the experimental.apk file uses the default "Android Debug" certificate. Maybe something went wrong with your build jobs?

This is the app-release.apk signature details for reference (not sure if the formatting will work in this comment):
