This behavior still exists in iOS 26.0.1 and iPadOS 26.0.1 even after upgrading the Apple Configurator host to macOS Tahoe 26.0.1. On every restart, "Software Update Complete" is displayed, along with: Your iPad has been updated to iPadOS 26.0.1. Your iPhone has been updated to iOS 26.0.1. Followed by the Welcome screen with the "Get Started" button. (Upgrading the Apple Configurator host to macOS Tahoe 26.0.1 did, however, fix the blank Profiles bug in Apple Configurator Version 2.18 10A23.)
