USDZ Files Rendered Incorrectly in VisionOS 2.1.1

At https://stetekluh.com/usd/ I have a number of USDA and USDZ files that render well with Preview on a Macintosh computer. The USDZ files also looked great in VisionOS 1.2. Except for the Utah teapot these files are not being rendered correctly in VisionOS 2.1.1. For example, my USD file for a soccer ball (https://stetekluh.com/usd/soccerball2colors-0.1x.usdz) defines hexagons and pentagons. These are rendered correctly with Preview on a Macintosh computer and with visionOS 1.2. In visionOS 2.1.1 the hexagons and pentagons are rendered as circles!
