I have spent time developing a MAUI project and have successfully released the android app for some time now but apple has been coming up with different issues.
See the description of the latest issues as reported in transporter.
Asset validation failed (91111)
Missing app icon. Include a large app icon as a 1024 by 1024 pixel PNG for the 'Any Appearance' image well in the asset catalog of apps built for iOS or iPadOS. Without this icon, apps can't be submitted for review. For details, visit: https://developer.apple.com/documentation/xcode/configuring-your-app-icon. (ID: eb3a7e69-d31c-4277-bec8-350e309412aa)
Asset validation failed (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 >= 10.0. To support older versions of iOS, the icon may be required in the bundle outside of an asset catalog. Make sure the Info.plist file includes appropriate entries referencing the file.
