I'm trying to submit my app and ran into this error:Missing Marketing Icon - iOS Apps must include a 1024x1024px Marketing Icon in PNG format. Apps that do not include the Marketing Icon cannot be submitted for App Review or Beta App Review.So, I updated my asset catalog to include one, but now I keep getting this error:ERROR ITMS-90717: "Invalid App Store Icon. The App Store Icon in the asset catalog in 'Some.app' can't be transparent nor contain an alpha channel."I have removed alpha and transparency with multiple Apps (Photoshop, pngcrush, imagemagick) but keep running into the validation error above. I'm pretty sure my PNG file does not contain any alpha channels or transparency at this point. The only way I found to pass validation is to supply the marketing icon in JPG format, contrary to the first error message.Anybody with similar issues or ideas how to pass validation with a PNG App Store icon?
