I get the folling error when trying to upload an app to TestFlight with an iMessage stickers extension with XCode 8.0 beta 3:ERROR ITMS-90644: "Missing Image Asset. Your app is missing the Large App Icon asset 'iMessage App Icon' in 'Payload/App.app/PlugIns/StickerPackExtension.appex'."Is ITC accepting TestFlight builds at the moment, or is there something wrong with my extension? I've allocated images to every space in my iMessages App Icon in my .xcstickers bundle.I did notice though that the various "settings" images and the 1024x768 "iMessages App Store" image don't make it through to the built .appex file though.
