Missing app icon

I have created a basic ios app with Animate. I have generated the icon Assets.car file and placed it in the included files scetion when publishing. When I try to upload the ipa file using Transporter I keep geting the same error.

ERROR ITMS-90022: "Missing required icon file. The bundle does not contain an app icon for iPhone / iPod Touch of exactly '120x120' pixels, in .png format for iOS versions >= 7.0."

I have checked to ensure this icon exsists when creating the Assets.car file but keep getting the error.

What am I missing?

Please help as this is becoming very frustrating!
