ERROR ITMS-90725 This app was built with ios 13.2 sdk[UE4-27]

i had a project where anytime i tried to test on ios i would get a black screen. I then Migrated the assets to a new project and now it is inexplicably working. When i package a shipping build and try to upload to testflight from the transporter app, it tells me “this app was built with the ios 13.2 sdk, all ios apps submitted to the app store must be built with the ios 15 sdk or later, included in Xcode 13 or later”. This wasnt happening in the last project, Whay does this mean and how do i fix this?

Hi! Any luck sorting this out?

((( ((( you found a fix for this? i dont understend unreal support sdk 15 for windos or not, and where can take this ?
