Hello.
We build and upload by xcode12, and at appstoreconnect We can't "Submit for Review" new builds in appstore for ios app:"A 1024 x 1024 pixel app icon for your app must be added to the asset catalog in Xcode".
But the 1024p icon exist in Xcode assets catalog.
Then we fllow the thread:654407 - https://developer.apple.com/forums/thread/654407 to fix the bug, but it does not work.
