Precomputed visibility not working in iOS build

Hi.

I am using Unreal 4.23 a the moment but I had this issue from .22.

I built and released a project on Android. All precomputed visibility works fine on PC, Android and mostly on Mac, but for the life of me, I can not get it to do anything in iOS.

I am testing on an iPhone 6 with all of its software up to date.

The last issues that I have are documented in the last two or so pages of this thread that I started.

Any help would be greatly appreaciated.
