xCode Error ITMS- 90086: Missing 64bit support / for my Unity App.

But if Unity Scripting backend is IL2CPP it won't build, so I have been told to put it as Mono 2X

which builds but gives me the xCode Error when trying to submit to iTunes Connect


ERROR ITMS-90086: "Missing 64-bit support. iOS apps submitted to the App Store must include 64-bit support and be built with the iOS 8 SDK or later. We recommend using the default "Standard Architectures" build setting for "Architectures" in Xcode, to build a single binary with both 32-bit and 64-bit support."

I should add ths only happens periodically :

Mostly I get the following message - it seems to happen frequently on these formuns but there is no "fix"


iTunes Store operation failed.

This action could not be completed. Try again.
