I need some help with iOS remote shader compile - "Loaded a text shader"

Hi all,

I’m hoping someone with some experience can help me figure out what I’ve misconfigured.

I’m seeing (In Xcode Console viewer) LogMetal: Display: Loaded a text shader (will be slower to load)
I’m Experiencing: Slow, jerky first launch of app (after install) the subsequent launches are okay. This seems to be due to the text shaders compiling on the device on first launch.

I think this relates to XGE Shader Compile needing to be disabled when packaging for iOs - but I’m out of my depth so may be miles off.

Because I never know where to post most effectively, the details are over in Answerhub

Please help get me on the right track if you can.
