altool error reported while uploading app bundle to testflight which is blocking the upload.
ERROR: [ContentDelivery.Uploader] Asset validation failed (90970) Missing Info.plist key. The App’s Info.plist file is missing the CFBundleIcons.CFBundlePrimaryIcon key for the visionOS App Icon. Add the key with the icon name as the value.
In the Unity Editor under “Project Settings → Player → VisionOS → Icon” the Icon dropdown cannot be expanded as it can for other platforms, so the app icon cannot be set there.
