App store submission says IDFA enabled when it isn't (4.24)

Hi all,
Have just tried to submit a UE4 project to the app store for review but have been told that it contains IDFA (Advertising Identifier). I’ve explicitly gone into the project settings and disabled IDFA but to no avail. I’m in 4.24 (mac, launcher version).

Has anyone any idea what might be up?

same in the 4.25.
