The mobile app experiences severe performance issues with extended load times. Specifically, the 'Join back in' button takes 23 seconds to load the screen after being clicked, and in-world UI elements such as the 'leave' button take 13 seconds to appear. These issues were tested across multiple worlds, including minimal/blank environments, with no improvement. The app version is 262.0.0.6.300, release build, and Cloud Pre-Warm is disabled. This issue is critical for mobile-only platform viability and requires resolution before VR deprecation.
