Hi All,
I'm submitting this question because I have explore all resources and couldn't find a solution on Window. I'm working with a developer as a designer to release an app on Appstore, the developer returned my app icon with an error to be fixed and I have checked I can't find where to remove alpha channel from my app icon image. Error ITMS-90717: "Invalid App Store Icon"
Please help and walk me through how I can remove alpha channel from the image in the attached file.
Thank you
